Question

Assertion (A): To generate only a part of the plant from a cell is totipotency.
Reason (R): Suitable special nutrient media and sterile conditions are required in in vitro conditions for the division of cells in explants.

• A. Both (A) and (R) are true and (R) is the correct explanation of (A).
• B. Both (A) and (R) are true, but (R) is not the correct explanation of (A).
• C. (A) is true, but (R) is false.
• D. (A) is false, but (R) is true.

Hint:

Totipotency means forming a whole plant, not just a part.

Answer 1

The Correct Option is D

Totipotency is the ability of a plant cell to regenerate into a complete plant, not just a part. So, the Assertion is false. However, division of plant cells in explants requires sterile, nutrient-rich media under in vitro conditions — making the Reason true.
