Short Answer Type Questions
Q.1. (a) Why is connective tissue called so?(b) What is the function of the areolar connective tissue?
(c) Which substance is present in the adipocyte? How does it help?
Ans. (a) These tissues connect various body organs. They connect bones to each other, muscles to bones and bind tissues. They are therefore called connective tissues.
(b) Areolar connective tissue are loose and cellular connective tissue. They act as a supporting and packing tissue between organs lying in the body cavity. They also help in repairing of tissues.
(c) Adipocytes are filled with fat globules. They keep visceral organs in position forming shock-absorbing cushions around them. Storage of fat also act as an insulator.
Q.2. State the location of apical meristem.
Ans. Apical meristem is present at the growing tips of stems and roots.
Q.3. Name the fluid matrix of a connective tissue.
Ans. Plasma.
Q.4. What are the functions of phloem?
Ans. Phloem transports food from leaves to other parts of the plant.
Q.5. Name the dead element of phloem.
Ans. Phloem fibres.
Q.6. State the difference between the tissue of the outer layer of the branch of a tree and the outer layer of a young tree stem.
Ans. The outer layer of a tree is made up of bark (dead cells) whereas outer layer of a young tree stem is made up of epidermis (living cells).
Q.7. (a) State any two differences between tendon and ligament.
(b) Give the function of adipose tissue.
Ans. (a) Differences:
| Tendon | Ligament |
| (i) It is strong and non-flexible. | (i) It is elastic and flexible. |
| (ii) It joins muscles to bones. | (ii) It joins bones to bones. |
| (iii) It is formed of white fibrous connective tissue. | (iii) It is fonned of yellow fibrous connective tissue. |

Long Answer Type Questions
Q.1. Write difference between animal tissue and plant tissue.
Ans.
| Plant Tissues | Animal Tissues |
| (i) Tissue organisation is towards stationary or fixed habit of plants. | (i) Tissue organisation is towards active locomotion of animals. |
| (ii) In plants, dead supportive tissues are more abundant. | (ii) In animals, living tissues are more abundant. |
| (iii) Plants need less maintenance energy as they are capable of making their own food. | (iii) Animals need more maintenance energy as they have to move in search of food. |
| (iv) There is differentiation of merismatic and permanent tissues. | (iv) Such differentiation is absent in animal tissue. |
| (v) Organisation is simple in plant. | (v) Organisation is complex in animal tissues due to the development of specialised organs and organ systems. |
| (vi) Growth is limited to certain regions. | (vi) Growth is not limited to a region in animals. |
Q.2. Based upon cell shape, cell wall and intercellular spaces, prepare a comparative study table between parenchyma, collenchyma and sclerenchyma. Which of these tissues is dead.
Ans.
| Parenchyma | Collenchyma | Sclerenchyma |
| (i) Living cells and isodiametric in shape. | Living cells, with thick corners. | Dead cells, long and narrow with tapered ends. |
| (ii) Cell walls are thin and made up of cellulose. | Cell walls are thickened at corners with extra deposition of cellulose and pectin. | Cell walls are thick due to heavy deposition of lignin. |
| (iii) Cells have distinct nucleus and a large central vacuole. | Cells have distinct nucleus and dense cytoplasm. | Cells do not have a nucleus and cytoplasm. |
| (iv) It stores food, waste products and forms packing tissue. | It gives mechanical support and flexibility. | It gives rigidity and mechanical strength to the plant. |
| (v) It is present in all soft parts of plant; i.e. in stems, roots, leaves, flowers and fruits. | It is present below the epidermis in stems and leaves. | It is present in xylem and phloem, in shells of nuts, in hard seeds, pulp of pear, etc. |
Sclerenchyma is a dead tissue.
Q.3. Answer the followings:
(a) Name the constituents of phloem tissues.
(b) Write the specific function of cardiac muscle.
(c) Name the tissue that:
(i) forms inner lining of our mouth.
(ii) forms soft parts of leaf, stem, root and fruit.
(d) Write two functions of adipose tissues.
Ans. (a) Phloem consists of four elements —
Sieve tubes, companion cells, phloem parenchyma and phloem fibres.
(b) Cardiac muscles show rhythmic contraction and relaxation of the heart and thus help to pump and distribute blood to various parts of the body.
(c) (i) Squamous epithelium
(ii) Parenchyma
(d) (i) It protects delicate organs.
(ii) Storage of fats helps it to act as an insulator and as a shock absorber.

FAQs on Class 9 Science Chapter 6 Previous Year Questions - Tissues
| 1. What are the main types of plant tissues? |  |
Ans. The main types of plant tissues are meristematic tissues and permanent tissues. Meristematic tissues are responsible for growth and are found in areas of the plant where growth occurs, such as tips of roots and shoots. Permanent tissues, on the other hand, are further divided into simple permanent tissues (like parenchyma, collenchyma, and sclerenchyma) and complex permanent tissues (like xylem and phloem), which perform specific functions in the plant.
| 2. What is the function of xylem in plants? | |
Ans. The function of xylem in plants is to transport water and dissolved minerals from the roots to the rest of the plant. Xylem also provides structural support due to the presence of lignin in its cell walls, which strengthens the tissue and helps the plant maintain its upright position.
| 3. How do meristematic tissues differ from permanent tissues? | |
Ans. Meristematic tissues are composed of actively dividing cells and are responsible for the growth of the plant. They are found in regions such as root tips and shoot tips. In contrast, permanent tissues consist of cells that have differentiated and are no longer dividing. These tissues perform specific functions and can be simple or complex, depending on their structure and role in the plant.
| 4. What are the characteristics of parenchyma tissue? | |
Ans. Parenchyma tissue is a type of simple permanent tissue characterized by its thin cell walls, large central vacuoles, and the ability to store nutrients, water, and starch. Parenchyma cells are involved in various functions, including photosynthesis, storage, and tissue repair. They can be found in various parts of the plant, including leaves, stems, and roots.
| 5. What role does phloem play in the plant's life? | |
Ans. Phloem is responsible for the transport of organic nutrients, particularly sugars produced through photosynthesis, from the leaves to other parts of the plant, including stems and roots. It consists of living cells that work together to ensure the distribution of essential nutrients throughout the plant, supporting growth and energy needs.
