Questions Covered in This Chapter
These NCERT Solutions answer all 52 questions of this chapter. The questions solved are:
- How is the study of cells and tissues significant for understanding the life processes and human welfare?
- How are tissues in plants and animals different, and why?
- How is the division of labour at various levels of organisation in multicellular organisms correlated with their structure and function?
- What trend do you observe in the data you recorded in Table 3.1? Are your observations similar to those presented in the graphical representation (Fig. 3.2)? What do you infer?
- What causes this increase in girth?
- What do you think happens to the growth of the plant if the tip of a young stem is cut?
- Why do you think that the cell of meristematic tissues lack vacuoles?
- What do you observe? Are all the cells similar in shape and size? How many different types of tissues can you identify? What differences do you notice among them? What might be the reason for the presence of different types of cells and tissues?
- What protects plants from mechanical injury, water loss, harmful microorganisms and extreme environmental conditions?
- What keeps a plant upright? Why does a fresh twig bend but a dry twig break? Why are seed coats hard and how do aquatic plants float?
- How does water reach the leaves of tall trees? How does food prepared in leaves reach other parts of the plant?
- You may have noticed that fibres of coconut husk are hard and brittle, whereas the leaf stalks of coriander are soft and flexible. Find out the reason.
- Why do you think that a thick cuticle on the outer wall of epidermis is advantageous for a plant living in the desert but disadvantageous for a plant living underwater?
- Once water is absorbed by plant roots, it has to travel against gravity through xylem. How do the ‘dead’ cells of the xylem work together with the living cells of leaves at the top to keep the water moving?
- What do you think will happen if there were no stomata in the epidermis of the stem or leaves?
- Now think, which tissue helps you move? Which tissue enables you to sense heat or cold? Which tissue allows oxygen to enter the blood? Which tissue holds the body together so that the skin does not fall off?

- Are there involuntary movements in the body?
- What percentage of total body weight comes from bones and muscles?
- Discuss why do bone and muscle mass differ between individuals, and how do they contribute to the overall body weight?
- Move different parts of your body and observe what movement(s) it can make.
- You may have noticed that some parts of our body can move easily in many directions, while others move only in a single direction. Why does this happen?
- So, what actually causes the bones to move?
- Look at the picture given below (Fig. 3.17). Carefully observe the various poses of classical and folk dances of India. Can you identify which joints are involved? Also, what type of movement each joint allows?
- What do you conclude about the characteristics of phloem cells of carrot?
- In which of the three combinations would you obtain the highest and lowest biomass? What could be the possible reason(s) for this observation?
- Will you get the same results if you culture animal cells instead of carrot cells?

- If a plant is unable to transport food from leaves to roots which tissue is malfunctioning? (i) Xylem (ii) Phloem (iii) Epidermis (iv) Sclerenchyma
- Why are the epithelial tissues that line an animal’s internal organs usually only one or a few cells thick? (i) To store food efficiently. (ii) To provide maximum strength. (iii) To allow quick exchange of materials across them. (iv) To reduce friction.
- You can perform these two jumps (Fig. 3.21): Straight-leg jump — keep knees and ankles stiff. Normal jump — bend knees and ankles naturally. How did your ankle, knee and hip positions differ between the two jumps?
- Which type of joint is involved when you bend your knees and ankles? (i) Ball and socket (ii) Hinge (iii) Pivot
- In each of the following cases (A, B, C and D), choose the correct option as given below: (i) Both (A) and (R) are true, and (R) is the correct explanation of (A). (ii) Both (A) and (R) are true, but (R) is not the correct explanation of (A). (iii) (A) is true, but (R) is false. (iv) (A) is false, but (R) is true. A. Assertion: Epithelium is well-suited for gas exchange in the lungs. Reason: It consists of multiple layers of tall cells that slow down diffusion. B. Assertion: Cardiac muscle can contract continuously without fatigue. Reason: Cardiac muscle cells have a high number of mitochondria and an abundant blood supply. C. Assertion: Tendons connect bone to bone and allow joint movement. Reason: Tendons are made of tough connective tissue that transmits force from muscle to bone. D. Assertion: In a hinge joint, movement occurs primarily in one plane. Reason: The bone ends are shaped to allow sliding in all directions.
- Plot a graph between the age of a tree (in years) on the x-axis and the diameter of the tree (in cm) along with the number of annual rings formed over time on the y-axis, using the data given in the Table 3.7. (i) Analyse the graph in terms of the diameter of the stem over time and share the interpretation. (ii) What is the relation between the diameter of the teak tree to the annual rings formed? (iii) Which specialised tissue is responsible for the girth of the stem and where is it located?
- In a forest, it was observed that one of the trees was severely debarked by an elephant to meet its food requirements, as the bark is a rich source of nutrients (Fig. 3.22). Based on your learning, answer the following: (i) Which function(s) of the tree is/are hampered by debarking? (ii) Which plant tissue would be affected by further damage to the tree trunk even after debarking? (iii) Which function of the tree would be hampered if the tissues beneath the bark were severely damaged? (iv) What assumptions are you making to answer the questions above? How would the answer change if your assumptions are also changed?

- Sohan designed an experiment for the regeneration of sugarcane, where he used cuttings to grow sugarcane. He used two types of cuttings, type ‘A’ and type ‘B’ (Fig. 3.23). After a few weeks, type ‘B’ cuttings sprouted and developed into sugarcane plants, whereas the type ‘A’ cuttings did not sprout. (i) Why were the type ‘B’ cuttings able to grow as sugarcane but type ‘A’ could not? (ii) What difference was present in type ‘B’ compared to type ‘A’? (iii) What observation or measurement was made to determine whether this change had an effect? (iv) What parameters should be kept the same for both types of cuttings to ensure a fair comparison?

(ii) Consult an elder community resource persons about their knowledge on different plant leaves, such as leaves that remain fresh for a long time, repel water or deter insects. Find out their traditional uses, such as making plates, preparing cooling wraps or functioning as insect repellents.
- Study various dance forms of different tribal communities across the country. Each student learn and experience at least five steps. Observe the joint movements involved in performing these steps and then develop a dance or drama on the concept of joint movements. Perform this at the school’s annual function so that students from different grades can learn from it.

Chapter at a Glance
- A tissue is a group of cells, similar in structure, that work together on one job. Cells → tissues → organs → organ systems → organism. This division of labour is what makes a large body efficient.
- Plant tissues are either meristematic (still dividing) or permanent (differentiated). Apical meristem adds length at root and shoot tips, lateral meristem adds girth, intercalary meristem lets grass and hedges regrow after cutting.
- Permanent tissues are simple (parenchyma, collenchyma, sclerenchyma — one cell type) or complex (xylem and phloem — several cell types working as one). The epidermis, with its cuticle, root hair and stomata, is the protective tissue.
- Plant tissues are organised into three tissue systems — dermal, ground and vascular.
- Animal tissues are of four kinds — epithelial, connective, muscular and nervous — and in each of them the structure fits the function exactly.
- The musculoskeletal system produces movement: a muscle contracts, a tendon carries that force to a bone, a ligament holds bone to bone, and the type of joint (ball and socket, hinge, pivot, fixed) decides how much movement is allowed. The nervous system controls the whole thing.
- Some mature plant cells are totipotent — they can dedifferentiate, divide and redifferentiate into a complete plant. This is the basis of plant tissue culture.
