ASSERTION AND REASON QUESTIONS (a) Both Assertion (A) and Reason (R) are true and Reason (R) is the correct explanation of the Assertion (A). (b) Both Assertion (A) and Reason (R) are true and Reason (R) is not the correct explanation of the Assertion (A). (c) Assertion (A) is true, and Reason (R) is false. (d) Assertion (A) is false, and Reason (R) True.

 

11	Assertion (A): Tissues give the highest possible efficiency of function. Reason (R): Tissues bring about division of labour in multicellular organisms.	1
12	Assertion (A): Growth of plants is restricted to certain specific regions. Reason (R): Plants have a large quantity of supportive tissue which is mostly made of dead cells.	1
13	Assertion (A): Meristematic tissues constitute the major portion of plant body. Reason (R): Meristematic tissues, after differentiation, give rise to permanent tissues.	1
14	Assertion (A): Permanent tissue are derived from meristematic tissue when they lose the ability to divide. Reason (R): Meristematic tissue is the dividing tissue in the growing regions of the plant.	1

CASE BASED STUDY QUESTIONS

 

34	Read the passage carefully and answer the following questions: A farmer noticed that the stems of his crops are bending towards the sunlight and the roots are growing deep inside the soil. He also observed that in sugarcane, water and food are transported efficiently from roots to leaves and from leaves to other parts of the plant.   1. Which plant tissues help the stem bend towards sunlight and the root grow deep into soil? 2. Name the tissues responsible for the transport of: a) Water and minerals b) Food 3. Which tissue provides mechanical strength to sugarcane stem? 4. Why do xylem vessels have thickened walls?	4
35	Read the passage carefully and answer the following questions: A patient met with an accident and his bone got fractured. The doctor advised him to take calcium-rich food and also suggested bed rest. In another case, a person suffered a cut injury, but after some days, his wound healed.   1. Which connective tissue connects bones to muscles and bones to bones? 2. Why is calcium important for the bones? 3. Which connective tissue helps in the healing of the wound? 4. Name the connective tissue that transports substances like oxygen and food in the human body.	4
36	Read the passage carefully and answer the following questions: A gardener observed that the outer surface of old trees becomes rough and hard. He also noticed that desert plants like cactus have a waxy layer on their surface.   1. Which protective tissue makes the outer bark of trees hard? 2. What is the role of cork in plants? 3. Name the tissue that forms a waxy coating on desert plants. 4. How does this waxy layer help plants survive in dry conditions?	4
