(4) Characteristic of Meristematic tissue

• Meristematic tissue are very active type of tissue.
• They have dense cytoplasm.
• The wall of Meristematic cells are thin cellulosic walls and prominent nuclei.
• They lack vacuoles.

(5) There are three types of meristematic tissue

• Apical Meristem
• Intercalary Meristem
• Lateral meristem

Meristematic tissue take up a specific role and lose the ability to divide. As a result, they form a permanent tissue. This process of taking up a permanent shape, size, and a function is called differentiation. Differentiation leads to the development of various types of permanent tissues.

Simple Permanent Tissue

Tissue made of one type of cells, which look like each other. Such tissues are called simple permanent tissue. Parenchyma is the most common simple permanent tissue. It consists of relatively unspecialised cells with thin cell walls. They are living cells. They are usually loosely arranged, thus large spaces between cells (intercellular spaces) are found in this tissue. This tissue generally stores food. In some situations, it contains chlorophyll and performs photosynthesis, and then it is called chlorenchyma . In aquatic plants, large air cavities are present in parenchyma to help them float. Such a parenchyma type is called aerenchym a.Yet another type of permanent tissue is sclerenchyma . It is the tissue which makes the plant hard and stiff. We have seen the husk of a coconut. It is made of sclerenchymatous tissue. The cells of this tissue are dead. They are long and narrow as the walls are thickened due to lignin.

Complex tissues are made of more than one type of cells. All these cells coordinate to perform a common function. Xylem and phloem are examples of such complex tissues. They are both conducting tissues and constitute a vascular bundle. Xylem fibres are mainly supportive in function. Phloem transports food from leaves to other parts of the plant. Except phloem fibres, other phloem cells are living cells.

(1) Tissue made of only one type of cell is termed as _________

(a) Simple permanent tissue

(b) Complex permanent tissue

(c) Simple Meristematic tissue

The covering or protective tissues in the animal body are epithelial tissues. Epithelium covers most organs and cavities within the body. External and Internal covering of the body and organs are all made of epithelial tissue.

Epithelial tissue cells are tightly packed and form a continuous sheet. They have only a small or almost no intercellular spaces.it plays an important role in regulating the exchange of materials between the body and the external environment and also between different parts of the body.

Simple squamous epithelial cells are extremely thin and flat and form a delicate lining. The oesophagus and the lining of the mouth are also covered with squamous epithelium. The skin, which protects the body, is also made of squamous epithelium.

Where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present. This columnar (meaning ‘pillar-like’) epithelium facilitates movement across the epithelial barrier. In the respiratory tract, the columnar epithelial tissue also has cilia, which are hair-like projections on the outer surfaces of epithelial cells. These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is thus ciliated columnar epithelium.

Cuboidal epithelium (with cube-shaped cells) forms the lining of kidney tubules and ducts of salivary glands, where it provides mechanical support. Epithelial cells often acquire additional specialisation as gland cells, which can secrete substances at the epithelial surface. Sometimes a portion of the epithelial tissue folds inward, and a multicellular gland is formed. This is glandular epithelium.

(1) The ciliated columnar epithelium is present in

(a) Respiratory tract

(b) Bile duct and oesophagus

(c) Fallopian tube and urethra

(d) Eustachian tube and stomach lining

Blood is a type of connective tissue. The cells of connective tissue are loosely spaced and embedded in an intercellular matrix. The matrix may be jelly like, fluid, dense or rigid. The nature of matrix differs in concordance with the function of the particular connective tissue.

Blood has a fluid (liquid) matrix called plasma, in which red blood corpuscles (RBCs), white blood corpuscles (WBCs) and platelets are suspended. The plasma contains proteins, salts and hormones. Blood flows and transports gases, digested food, hormones and waste materials to different parts of the body.

Bone is another example of a connective tissue. It forms the framework that supports the body. It also anchors the muscles and supports the main organs of the body. It is a strong and nonflexible tissue. Bone cells are embedded in a hard matrix that is composed of calcium and phosphorus compounds. Two bones can be connected to each other by another type of connective tissue called the ligament. This tissue is very elastic.

Another type of connective tissue, cartilage, has widely spaced cells. The solid matrix is composed of proteins and sugars. Cartilage smoothens bone surfaces at joints and is also present in the nose, ear, trachea and larynx.

Areolar connective tissue is found between the skin and muscles, around blood vessels and nerves and in the bone marrow. It fills the space inside the organs, supports internal organs and helps in repair of tissues.

(1) A connective tissue

(a) Has no matrix

(b) Covers the skin

(c) Has abundant matrix

(5) Examples of connective tissue

Muscular tissue consists of elongated cells, also called muscle fibres. This tissue is responsible for movement in our body. Muscles contain special proteins called contractile proteins, which contract and relax to cause movement

We can move some muscles by conscious will. Such muscles are called voluntary muscles. These muscles are also called skeletal muscles as they are mostly attached to bones and help in body movement. Under the microscope, these muscles show alternate light and dark bands or striations, hence they are also called striated muscles. The cells of this tissue are long, cylindrical, unbranched and multinucleate.

The movement of food in the alimentary canal or the contraction and relaxation of blood vessels are involuntary movements. We can’t control these muscle movement. The Smooth muscles or involuntary muscles control such movements. They are also found in the iris of the eye, in ureters and in the bronchi of the lungs. The cells are long with pointed ends (spindle-shaped) and uninucleate. They are also called unstriated muscles.

The muscles of the heart show rhythmic contraction and relaxation throughout life. These involuntary muscles are called cardiac. Heart muscle cells are cylindrical, branched and uninucleate.

(1) Which of the following muscle tissue are voluntary in nature?

(a) Cardiac muscle

(b) Smooth muscle

(c) auto rhythmic muscle

(d) None of the above

(2) The muscles whose contraction is under our control are known as

Phloem: Conduct food to all parts of plant. Consist of sieve tubes, companion cell, phloem parenchyma and phloem fibres.

2: Show the types of animal tissues using flow chart. Answer:

3: What is connective tissue? Explain its types.

Answer:  The connective tissue consists of different types of cells, all of them perform same function.

Areolar connective tissue: It is found between the skin and muscles, around blood vessels and nerves and in the bone marrow. Areolar tissue fills the space inside the organs. It supports internal organs and helps in repair of tissues.

Adipose tissue: Adipose tissue stores fat, found below the skin and between internal organs. The cells of this tissue are filled with fat globules. It acts as insulator due to fat storage.

Blood:  It has a fluid called plasma, in plasma are present red blood cells, white blood cells and platelets. Blood flows all over the body and helps in the transport of gases, digested food, hormones and waste material to different parts of the body.

Lymph:  Lymph carries digested fat and lot of white blood cells in the plasma. Bone: It forms the framework that supports the body. It supports the different parts of our body. It is strong and non-flexible tissue.

Cartilage:  It is present in nose, ear, trachea and larynx. It smoothens bone surfaces at joints.

Tendon:  It connects bone and muscles. These tissues are fibrous, flexible and with lot of strength.

Ligament:  It connects bone to ‘bone. It is elastic, has lot of strength.

4: Describe ‘epidermis’ in plants.

Answer:  Epidermis forms the entire outermost layer of the plant. It is made up of single cell layer. It protects all the internal parts of the plant. On aerial parts, epidermis secretes waxy, water-resistant layer on their outer surface. This helps in protection against loss of water, mechanical injury and invasion of parasitic fungi.

In leaves, epidermis consists of small pores called stomata. These pores help in the transpiration and exchange of gases, like oxygen and carbon dioxide for plants. In roots, epidermis have long hair-like parts that provide greater surface for water absorption. In desert plants, epidermis has a thick waxy coating of cutting which acts as a water proofing agent.

5: Explain the “complex tissue” of plants.

Answer:  Complex tissues are made up of more than one type of cells. All these cells co-ordinate to perform common function. These are—xylem and phloem. Both are conducting tissues and form a vascular bundle.

Xylem consists of—tracheids, vessels, xylem parenchyma and xylem fibres. Most of these cells are dead. Tracheids and vessels helps in water transportation, parenchyma stores food and helps in the sideways conduction of water and fibres are mainly supportive in function. Phloem is made up of four types of elements—sieve tubes, companion cells, phloem fibres and phloem parenchyma. It helps in the transportation of food in both the directions, i.e. from leaves to roots and to other parts of the plant.

Long Answer Questions

49. Differentiate between sclerenchyma and parenchyma tissues. Draw a well-labeled diagram.

Ans: The difference between parenchyma and sclerenchyma tissues: 

Various types of simple tissues: (a) Parenchyma (b) Collenchyma (c) Sclerenchyma transverse section (d) longitudinal section.

50. Describe the structure and function of different types of epithelial tissues. Draw diagrams of each type of epithelial tissue.

Ans: The human body consists of four types of tissue: epithelial, connective, muscular and nervous. Epithelial tissues are thin and cover all the exposed surfaces of our body, and keep different body systems separate. Epithelial tissues form the skin, the inner lining of the mouth, digestive tract, the lining of blood vessels, lung alveoli and kidney tubules, the lining of hollow parts of every organ such as heart, lungs, eyes, ears, the ventricular system of the brain, central canals of the spinal cord are all made of epithelial tissue.

Epithelial tissue cells are closely bound to one another with only a small amount of cementing material between them and almost no intercellular spaces.

They perform several functions such as protection from invasion of various pathogens, radiation damage, abrasion, excretion, filtration, diffusion etc. The permeability of the cells of various epithelia plays a part in regulating the exchange of materials between the body and the external environment and also between different parts of the body.

Different types of epithelial tissues are as follows:

(1) Simple squamous epithelium

(2) Stratified squamous epithelium

(3) Columnar epithelium, and

(4) Cuboidal epithelium.

These are simple, thin, single-layered, delicate and flat types of cells. Simple squamous epithelial cells are selectively permeable, form lining blood vessels, alveoli and lungs i.e. where transportation of substances takes place. Simple squamous epithelial cells also form the lining of the oesophagus, the skin and the mouth.     

These are multilayered, cells from multiple layers. Skin is made up of these issues. Stratified squamous cells are compactly placed in order to avoid wear and tear of the skin cells.

(3) Columnar epithelium

These cells are longitudinal, pillar-like and have outstretched nuclei. These cells are found where absorption and secretion occur, such as in the intestine’s inner lining.

Ciliated Columnar epithelium: Hair-like projections are found on the external surface of the epithelial cells, these projections are called cilia. These cilia are capable of movement and their movement pushes the substance forward. The ciliated columnar epithelium is found on the lining of the oviduct, lining of the trachea, kidney, etc.

(4) Cuboidal epithelium

These cells are cuboidal (cube-like) in shape.  Cuboidal epithelial cells provide mechanical support and form the lining of kidney tubules. These cells also form the lining of salivary glands.

Glandular Epithelium: Epithelial cells often evolve into gland cells. The glandular epithelium is found in tear and sweat glands. They perform the function of secretion.

51. Draw well-labelled diagrams of various types of muscles found in the human body.

Ans: (a) Striated muscle

(b)  Smooth muscles

(c)  Cardiac muscles

52. Give reasons for

(a) Meristematic cells have a prominent nucleus and dense cytoplasm but they lack vacuole.

Ans: Meristematic cells have prominent nuclei and dense cytoplasm, they continue diving throughout their lifetime. Meristematic cells divide constantly and give rise to new cells hence they do not need to maintain a definite shape and store food or accumulate waste material. Therefore, vacuoles are absent in meristematic cells.

(b) Intercellular spaces are absent in sclerenchymatous tissues.

Ans: Intercellular spaces are absent in sclerenchymatous tissues because they have lignified cell walls. They are organized closely and are meant to provide strength and protection to the plant parts.

(c) We get a crunchy and granular feeling when we chew pear fruit.

Ans: Sclerenchymatous tissues are present in pear fruit. They are small, thickened and hard due to the presence of lignin. As a result, we get a crunchy and granular feeling when we chew pear fruit. 

(d) Branches of a tree move and bend freely in high wind velocity.

Ans: Branches of a tree bend freely in high wind velocity due to the presence of collenchyma. Collenchyma is present at the junction of branches. It provides rigidity with flexibility.

(e) It is difficult to pull out the husk of a coconut tree.

Ans: The husk of a coconut tree is made up of sclerenchymatous tissues.  Sclerenchyma cells are lignified and are packed densely for the protection of the plant. Hence, it is difficult to pull out the husk of a coconut tree.

53. List the characteristics of cork. How are they formed? Mention their role.

Ans: a) Characteristics of cork are as follows:

It is an outer protective tissue layer of the oldest stem.

Cork cells are dead at maturity.

Cells are compactly arranged and cells do not have intercellular spaces.

A chemical substance called Suberin is present in their cell walls.

Cells are thick and made up of several layers

b) At maturity,  secondary meristem replaces the epidermis of the stem. Cells that are cut on the outer side by this meristem are then called cork.

c) The Main function is to provide protection to older stem/twigs/branches and prevent water loss. The tick material is impervious to water and works as an insulator.

54. Why are xylem and phloem called complex tissues? How are they different from one another?

Ans: A tissue made up of more than one or more types of cells and they work together as a unit is known as Complex tissue. Both xylem and phloem are made up of more than one type of cell and that's why they are known as complex tissues.

55. (a) Differentiate between meristematic and permanent tissues in plants.

(b) Define the process of differentiation.

Ans: Differentiation is a process in which the cell loses its ability to divide and takes up a permanent shape, size and function. Young cells evolve to become specialized cells, develop into tissues and organs with the help of differentiation. 

(c) Name any two simple and two complex permanent tissues in plants.

Ans: (i)The two simple tissues in plants are: Parenchyma/collenchyma/sclerenchyma.

(ii) The two complex tissues in plants are xylem/phloem.

Quick Review of Chapter 6 Tissues 

• Living organisms in this world comprise cells.
• There are unicellular as well as multicellular organisms present in this world.
• In unicellular organisms, the single cell is capable of performing several functions such as respiration, digestion and clearing of the cell.
• In multicellular organisms, there is a division of labour. There are different types as well as groups of cells that perform different functions in a multicellular organism. 
• For Example, In animals muscle cells are responsible for causing movement, nerve cells are responsible for carrying messages and signals from one part of the body to another and blood is responsible for the transportation of food and oxygen to different parts of the body.
• In plants, there are vascular tissues that are responsible for carrying food and water to two different parts of a plant.

The formation of tissues.

• The cells form groups of cells to perform a single task.
• This grouping of cells together to perform a function efficiently is called a Tissue.
• For Example, Muscles and Blood.
• The tissue cells have the same structure and they perform the same function.

Tissues of Plants and Animals

Plant tissues.

Figure 1: Types of Plant Tissues  

Meristematic Tissue

• Only certain parts of a plant tend to grow. The tissues located in such parts are called meristematic tissues.
• They can divide themselves and form new tissues. 
• They have a thin cell wall made of cellulose.
•  They have a dense nucleus and cytoplasm but lack vacuoles.
• Intercalary

Figure 2: Location of meristematic tissue

Why are there no vacuoles in the intercalary meristem?

• Vacuoles are responsible for the storage of food in the water. The intercalary tissues do not store them. They are rather responsible for manufacturing them.
• Moreover, vacuoles contain sap which provides rigidity to a cell. This property of vacuoles may not allow the intercalary tissues to divide and manufacture new cells. Hence vacuoles are not present in them.

Permanent Tissue

• The cells that are formed by the meristematic tissues often have to take a certain role in the plant and thus, they lose their ability to divide and form more cells. They then become the permanent tissues of the plants.
• Differentiation - The process by which cells of the meristematic tissues convert themselves into permanent tissue by taking a fixed shape, size and function is called differentiation.
• Simple Permanent Tissues

Complex Permanent Tissues

Chlorenchyma

• Collenchyma
• Sclerenchyma

Figure 3: Simple Permanent Tissue

• These tissues are similar to that of parenchyma but they also contain chlorophyll in them.
• Due to the presence of chlorophyll, they are capable of performing the process of photosynthesis in plants.
• They are found in aquatic plants.
• They are also similar in structure to that of the parenchyma but they have large air cavities in them.
• These cavities allow the aquatic plants to float in water.

What is Lignin?

The cell walls of dead cells have a substance called lignin in them which provides rigidity to the cells. Lignin acts as the cement for the cells.

• The outermost layer of the cell is known as the Epidermis.
• It covers the entire plant.
• It is a thin layer of single cells but in places with less water, the epidermis of the plants can become thick in order to avoid frequent water loss.
• The cells are flat and they have no intercellular spaces between them.
• The outer walls of the epidermal cells are thick and the inner walls are thin.
• The epidermal cells often have long hair-like structures in roots which facilitate the absorption of water.
• The main function of the epidermis is to protect the plants from fungi, water loss and any injuries by secreting a wax-like water-resistant substance called a Cuticle on the surface of the plants which protects the plants.

Figure 4: Epidermis

• Stomata are pore-like structures that are present in the epidermis of the leaves.
• These pores are enclosed by two cells that have a similar shape as a kidney. These are called Guard Cells of Stomata. Guard cells are modified epidermal cells.
• Guard cells are responsible for the exchange of gases and transpiration.

Transpiration (OLYMPIAD)

Figure 5: Transpiration

The plant cells sometimes have extra they lose it in the form of water that evaporates through stomata. This process is called Transpiration.

Role of Transpiration in Plants – (OLYMPIAD)

• Exchange of Gases - Plants absorb carbon dioxide and release oxygen through transpiration.
• Prevent the Plants from Overheating - The leaves absorb sunlight during the process of photosynthesis. Some of it is used in the photosynthesis process while the rest is radiated as Heat Energy. We know that absorption of water causes cooling of the surrounding area. Therefore transpiration keeps the leaves cool.
• Transportation of Food and Water in Plants - The roots of the plants absorb minerals and water present in the soil through transpiration and they are then distributed in the plant through the transpiration stream.
• Movement of Water in Plants – As plants lose water in the form of water vapours, the density of water in leaves becomes low. So the water from the higher density areas such as the roots move up to lower density areas through a force called Transpirational Pull.

Which gas is necessary for the process of photosynthesis?

Carbon dioxide gas is necessary for the process of photosynthesis. Plants use carbon dioxide along with water and sunlight to produce glucose in the process of photosynthesis. Plants take in carbon dioxide and release oxygen as a byproduct of the photosynthesis process.

Why do plants in desert areas have a waxy coating of cutting over them?  (OLYMPIAD)

The epidermis cells of plants that are found in deserts have a waxy coating of cutting over them because it prevents water loss from the surface of plants since water is already scarce in such areas.

Why are the branches of old trees different from the stems of a new plant?

• As a plant grows older the meristematic cells start covering the upper layer of the plants instead of the epidermis.
• These are the dead cells that have no special function in the plants but to provide rigidity. They make the branches of the plants thick.
• This is often called the Bark or the thick cork of the tree.
• The bark of the trees contains a substance called Suberin which makes it waterproof and does not allow gaseous exchanges. (OLYMPIAD)

Complex Permanent Tissues comprise different kinds of cells. These different types of cells coordinate with each other and perform a common function in these tissues. Two Complex Permanent Tissues are - Xylem and Phloem.

Figure 6: Xylem and Phloem  

Similarities between Xylem and Phloem

• Their main function is to carry food and water in the plant.
• Both have a vascular bundle which is a conductive tissue in plants that helps them survive in different environmental conditions.

Xylem is made up of dead cells having a thick cell lining. It consists of the following elements-

• Tracheids and Vessels – They have a broad tubular structure so that we can allow transportation of food and water in the plants vertically.
• Xylem Parenchyma – It stores food and helps in the transportation of water horizontally in the plants.
• Xylem Fibres – They support transportation

Phloem is made up of living cells and it allows the movement of food from leaves to other parts of the plant. It has the following elements –

Sieve Tubes – Broad shaped cells with porous walls

• Companion Cells – They facilitate the functions of the sieve tubes
• Phloem Fibres – Provide flexibility to the phloem
• Phloem Parenchyma – Stores starch and proteins

Animal Tissue

Figure 7: Types of Animal Tissues

1. Epithelial Tissue

• They are the protective tissues of the human body. They cover many organs and cavities that are present inside the body.
• The lining of the blood vessels
• The lining of the mouth
• Kidney tubules
• Lung alveoli
• The main function of the epithelial tissues is to act as a barrier and separate different organs and systems from each other.
• There is no space between the cells of epithelial tissues
• The cells are permeable. This makes it possible for them to exchange materials between different parts of the body and also between the body and the external environment.
• The epithelial tissues remain separated from the tissues beneath them because of a thin membrane over them.

Figure 8: Types of Epithelium

2. Connective Tissues

Structure and function of connective tissues

• They are loosely bound cells present in an intercellular Matrix.
• This matrix can be of different types – Dense, Rigid, Fluid or Jelly-like.
• Depending upon the functionality of the connective tissue, the nature of the matrix varies.

Examples of Connective Tissues

Figure 9: Connective Tissues

The main function of blood is to transport gases, food, waste materials and hormones in the body.

Therefore, blood has a fluid Matrix present in it which is called Plasma.

The plasma contains red blood cells, white blood cells and blood platelets.

The RBC has haemoglobin pigment which carries oxygen to tissues.

White blood cells fight diseases and platelets are involved in the clotting of blood when injured.

The plasma also contains proteins and hormones in it.

Lymph (OLYMPIAD)

Lymph is a colourless fluid that carries white blood cells throughout the human body in lymphatic vessels. There are lymphoid organs present in the body that produce lymph and together form the lymphatic system. Some of them are lymph nodes and tonsils.

Figure 10: Lymph Capillaries

Lymph is similar to blood except for a few differences:

• It contains only white blood cells.
• It contains less amount of blood proteins, calcium and phosphorus but more glucose.
• It flows in one direction only.
• Lymph moves in the body through its normal function, unlike blood which is pumped by the heart.

Constituents of Lymph:

Lymph Plasma – Lymph Plasma carries infection-fighting proteins along with other substances such as water, calcium and phosphorus.

Lymph Corpuscles – Lymph Corpuscles comprises white blood cells. Red blood cells and platelets are not present in lymph.

Functions of Lymph:

• It carries oxygen and minerals to the cells in the body and carries back carbon dioxide and waste materials back into the blood.
• It keeps the body cells moist.
• It maintains the volume of the blood.
• It helps in eliminating harmful bacteria and viruses from the body and hence is responsible for the immunity of human beings.
• It absorbs fats from the intestine and transports them throughout the body.
• Bones form a framework of the body over which the muscles are wrapped together.
• The bone tissue is strong and inflexible.
• Therefore, the bone cells are present in a rigid matrix that is formed from calcium and phosphorus.

Haversian Canals (OLYMPIAD)

Figure 11 Haversian Canal

• The bones comprise microscopic tubes called Haversian Canals.
• They are contained in osteons, rough cylindrical structures present along the axis of the bone.
• They allow the blood vessels, lymphatic vessels, and nerve fibres to travel through them.
• These canals have concentric channels called Lamellae around them.
• The Haversian canals communicate with bone cells through connections called Canaliculi.
• Cartilage is present over the joints of the bones and provides them with a smooth structure.
• For Example in the nose tip and ear pinna, trachea, larynx.
• They contain a solid matrix made of protein and sugar. They have a homogenous matrix.
• It provides support and flexibility to various parts of our body.
• A ligament connects two bones together.
• It has an elasticity that facilitates the connection.
• The cells of ligaments have a little matrix.
• The tendon tissues are responsible for connecting bones and muscles together.
• They have limited flexibility but very great strength.
• This tissue acts as a filter in between the spaces present inside the organs of the body.
• It helps in repairing other tissues as well.
• It is found in the skin and bone marrow.

Components of the Areolar Connective Tissue

Figure 12 Components of the areolar connective tissue

1. Cells (OLYMPIAD)

• Fat Cells (Adipocytes) – They are responsible for the secretion of lipids.
• Fibroblasts – They are present in the highest amount in areolar tissues. They are responsible for the secretion of fibres.
• Mast Cells – They release histamine that plays a role in allergic reactions
• Macrophages – They eat any germs or infectious cells in the body
• Plasma Cells – They produce antibodies
• Collagen Fibres – They provide tensile strength to the tissue
• Elastin Fibres – They provide elasticity to the tissue
• Ground Substance – It is a fluid matrix that holds cells and fibres of the tissue
• Fats are stored in our body in the adipose tissues.
• They are found below the skin and between the organs of the body.
• Provides cushioning to the organs.

3. Muscular Tissue

• It is made up of muscle fibres which are long cells.
• It allows movements in our bodies.
• How can muscles cause movement?

They contain special proteins called Contractile Proteins. These proteins cause contraction and relaxation of the muscles.

• There are two kinds of muscles found in our body - Voluntary Muscles and Involuntary Muscles.

Figure 13: Muscular Tissue

Cardiac Muscles

• These are special kinds of involuntary muscles.
• The muscles of the heart are called Cardiac Muscles. They perform rhythmic contraction and relaxation throughout our life.
• They are cylindrical in shape, they have branches and there is a single nucleus.
• Cardiac muscle consists of individual heart muscle cells connected by intercalated discs to work as a single functional organ

4. The Nervous Tissue

• This is because of the nervous tissues present in our body. They are capable of transmitting information quickly from the brain to different parts of the body and vice-versa.
• Therefore nervous tissues are found in nerves, brain, and spinal cord.
• Nervous tissue is made up of cells called the Nerve Cells or Neurons.
• These neurons connect together to form the nerves of our body.
• It is an elongated cell with a Cell Body that consists of some branch-like structure called Dendrites.
• There is a Nucleus present in the centre of the cell body.
• The Nerve Endings of the cell are connected with the cell body via Axon.
• A nerve cell can be up to 1 m long.

Figure 14: Structure of Neuron  

The Structure of Neuron

1. Dendrites

• They are tree-like extensions (highly-branched) at the beginning of a neuron.
• They increase the surface area of the neuron.
• They receive chemical signals from different neurons of the body.
• They then convert these chemical signals into electrical signals and pass them to the neuron cell body.
• A neuron can have a single dendrite or multiple dendrites

2. Cell Body

• Also called Soma.
• The main function of the cell body and nucleus of the neuron is to maintain the functionality of the cell.
• It does not play an active role in the transmission of the signal.
• It produces proteins that are required by different parts of the neuron to work properly.
• It contains different cell organelles such as mitochondria, Golgi apparatus etc that perform various functions of the cell.
• Neurons have one axon in general.
• It is a long structure that connects the cell body to the terminals and it also connects with other neurons, cells and organs of the body through nerve terminals.
• It allows for the fast transmission of signals. The larger the diameter of the axon the faster it will transmit signals.
• It is covered with a special insulating substance called myelin. It helps in the rapid transmission of signals.

4. Schwann Cells (OLYMPIAD)

• The Myelin sheath that covers the axon is produced by Schwann cells.
• The Myelin sheath keeps the signal intact.

Question. Differentiate between sclerenchyma and parenchyma tissues. Draw well labelled diagram. Answer.

Question.  If a potted plant is covered with a glass jar, water vapours appear on the wall of glass jar. Explain why? Answer.  Transpiration takes place through stomata. Water vapour comes out of leaves during transpiration. When a potted plant is covered with a glass jar, water vapour (coming out becomes of transpiration) condenses on the wall of glass jar and hence it appears as fine droplets.

Question. Describe the structure and function of different types of epithelial tissues. Draw diagram of each type of epithelial tissue. Answer. Epithelial tissues are the covering or protective tissues in the animal body. Epithelium covers most organs and cavities within the body and keep different body systems separate. The skin, the lining of the mouth, the lining of blood vessels, lung alveoli and kidney tubules are all made of epithelial tissue. Epithelial tissue cells are tightly packed and form a continuous sheet. They have only a small amount of cementing material. between them and almost no intercellular spaces. The permeability of the cells of various epithelia play an important role in regulating the exchange of materials between the body and the external environment and also between different parts of the body. Regardless of the type, all epithelia are usually separated from the underlying tissue by an extracellular fibrous basement membrane. Epithelial tissues are of following types— (1) Simple squamous epithelium (2) Stratified squamous epithelium (3) Columnar epithelium, and (4) Cubodial epithelium. These tissues differ in structure that correlate with their unique functions. For example, in cells lining blood vessels or lung alveoli, where transportation of substances occurs through a selectively permeable surface, there is a simple flat kind of epithelium. This is called the simple squamous epithelium. Simple squamous epithelial cells are extremely thin and flat and form a delicate lining. The skin, oesophagus and the lining of the mouth are also covered with squamous epithelium. Skin epithelial cells are arranged in many layers to prevent wear and tear. Since, they are arranged in a pattern of layers, the epithelium is called stratified squamous epithelium. Where absorption and secretion occur, as in the inner lining of the intestine, tall epithelial cells are present. This columnar epithelium facilitates movement across the epithelial barrier. In the respiratory tract, the columnar epithelial tissue also has cilia, which are hairlike projections on the outer surfaces of epithelial cells. These cilia can move, and their movement pushes the mucus forward to clear it. This type of epithelium is thus ciliated columnar epithelium. Cuboidal epithelium forms the lining of kidney tubules and ducts of salivary glands, where it provides mechanical support. Epithelial cells often acquire additional specialisation as gland cells, which can secrete substances at the epithelial surface. Sometimes a portion of the epithelial tissue folds inward, and a multicellular gland is formed. This is glandular epithelium.
