(a) aerenchyma and (b) chlorenchyma.
Q 2. Where is the apical meristem found?
Answer:
The apical meristem is found at the growing tips of roots and shoots of plants. Its main function is to increase the length of the stem and root by initiating the growth of new cells.
Q 3. Which tissue makes up the husk of coconut?
Answer:
The husk of a coconut is made up of sclerenchyma tissue. It is a permanent tissue whose cells are dead.
They are long and narrow as the walls are thickened due to lignin. This tissue makes the husk hard and thick.
Q 4. What are the constituents of the phloem?
Answer:
Phloem is a conducting or vascular tissue of the plants which transports food from leaves to other parts of the plant. Phloem is made up of four types of elements:
(i) sieve tubes (ii) companion cells (iii) phloem fibers and (iv) phloem parenchyma.
Out of these four, only phloem fibers are dead cells.
Q 1. Name the tissue responsible for movement in our body.
Answer:
The muscular tissue is responsible for movement in our body.
Muscular tissue consists of muscle fibres which are elongated cells. The movement is caused when these muscles contract and relax.
Q 2. What does a neuron look like?
Answer:
Neurons or nerve cells are the structural and functional unit of the nervous tissue. The brain, spinal cord, and nerves are all composed of the nervous tissue.
A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise. Each neuron consists of axons, a single long part (process), and dendrites, which are the short, branched parts (processes).
The axon transmits impulses away from the cell body, whereas the dendrite receives nerve impulses from other nerve cells or external stimuli.
Q 3. Give three features of cardiac muscles.
Answer:
Heart, which pumps blood throughout the body, is made up of cardiac muscles. Three features of cardiac muscle are:
(i) Cardiac muscles are involuntary. They cannot be controlled by a will.
(ii) Cardiac muscle cells are cylindrical, branched and uninucleate.
(iii) Cardiac muscles show rhythmic contraction and relaxation throughout life.
Q 4. What are the functions of areolar tissue?
Answer:
Areolar tissue is a connective tissue that fills the space inside the organs, supports internal organs and helps in the repair of tissues. It is found between the skin and muscles, around blood vessels and nerves and in the bone marrow.
Class 9 Science Chapter 6 Exercise Question Answers are given below in the best possible way in easy language including flowcharts.
Q 1. Define the term “tissue”.

Q 2. How many types of elements together make up the xylem tissue? Name them.
Answer:
Xylem transports water and minerals vertically from the roots to various parts of the plants. Xylem tissue consists of four different types of cells:
(i) Tracheids (ii) Vessels (iii) Xylem Parenchyma (iv) Xylem fibres
Out of these four, only Xylem Parenchyma is a living cell.
Q 3. How are simple tissues different from complex tissues in plants?
Answer:
Simple tissues are different from complex tissues in plants in the following ways
Simple tissues | Complex tissues |
Simple tissues are composed of a single type of cells. | Complex tissues are composed of cells of more than one type. |
These tissues are protective and supportive in function. | The function is the conduction of water, minerals and food products to different parts of the body |
Three types of simple tissues are: parenchyma, collenchyma, and sclerenchyma | Two types of complex tissues are: Xylem and Phloem |
Q 4. Differentiate between parenchyma, collenchyma and sclerenchyma on the basis of their cell wall.
Answer:
Parenchyma | Collenchyma | Sclerenchyma |
The cell wall is thin and are very loosely packed. | The cell wall is thick at corners with very little space between cells. | The cell wall is thick uniformly with no intercellular spacings. |
Cell Wall is Primary | Cell Wall is Primary | The cell wall is Secondary |
Cell wall made up of cellulose | The cell wall is made up of pectin and hemicellulose | The cell wall has an additional layer of lignin. |
Q 5. What are the functions of the stomata?
Answer:
Stomata are the small pores on the surface of the leaf. Functions of the stomata are :
(i) They allow the exchange of gases (CO 2 and O 2 ) with the atmosphere.
(ii) Transpiration (loss of water in the form of water vapour) also takes place through stomata.
Q 6. Diagrammatically show the difference between the three types of muscle fibres.
Answer:
The three types of muscle fibers are:
(i) Striated muscle
(b) Smooth muscle (Unstriated)
(c) Cardiac muscle
Q 7. What is the specific function of the cardiac muscle?
Answer:
The cardiac muscles are present in the wall of the heart.
The specific function of the cardiac muscle is to control the continuous rhythmic contraction and relaxation of the heart.
Answer:
Striated Muscle | Unstriated Muscle | Cardiac Muscle |
These are voluntary muscles. | These are involuntary muscles. | These are involuntary muscles. |
The cells are long, cylindrical. | The cells are long with pointed ends. | The cells are cylindrical. |
Cells are unbranched | Cells are unbranched | Cells are branched |
Cells are multinucleate. | Cells are uninucleate. | Cells are uninucleate |
These muscles are present in limbs and join the bones. | These muscles are found in the alimentary canal, bronchi of the lungs, etc. | These muscles are only found in the wall of the heart. |
Q 9. Draw a labelled diagram of a neuron.
Answer:
A neuron consists of a cell body with a nucleus and cytoplasm, from which long thin hair-like parts arise. Each neuron consists of axons, a single long part (process), and dendrites, which are the short, branched parts (processes).
The axon transmits impulses away from the cell body, whereas the dendrite receives nerve impulses from other nerve cells or external stimuli.

Q 12. Name the regions in which parenchyma tissue is present.
Answer:
The parenchyma tissue is present in leaves, fruits, and flowers.
Parenchyma is the most common simple permanent tissue consisting of relatively unspecialized cells with thin cell walls (living cells). This tissue generally stores food and chlorophyll.
Q 13. What is the role of the epidermis in plants?
Answer:
The epidermis is the outermost layer of cells of a plant body. The epidermis is usually made of a single layer of cells.
Following are the roles of the epidermis:
1. The entire surface of plants living in very dry habitats has an outer covering of epidermis to protect against water loss.
2. To protect against loss of water, mechanical injury and invasion by parasitic fungi, epidermal cells on the aerial parts of the plant often secrete a waxy, water-resistant layer on their outer surface.
3. Stomata present on epidermis help in gaseous exchange and transpiration.
Since it has a protective role to play, epidermal tissue cells form a continuous layer with no intercellular space.
Q 14. How does the cork act as a protective tissue?
Answer:
Cork is the outer protective layer of the bark of a tree. The cork cells are dead and compactly packed with no intercellular space. Their cell walls are coated with a waxy substance, suberin, which does not allow water and gases to pass through.
Therefore, it protects the plant against mechanical injury and also prevents the loss of water by evaporation.
Q 15. Complete the following chart:
Answer:
Simple permanent tissue is of three types: Parenchyma, Collenchyma and Sclerenchyma
Complex permanent tissue is of two types: Xylem and Phloem
Thus, the completed chart is :
