Q. Given below are two statements : one is labelled as Assertion (A) and the other is labelled as Reason (R). Assertion (A): Cells of the tapetum possess dense cytoplasm and generally have more than one nucleus. Reason (R): Presence of more than one nucleus in the tapetum increases the efficiency of nourishing the developing microspore mother cells. In the light of the above statements, choose the most appropriate answer from the options given below:
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
Explanation
[Solution by Claude - not from source] A is true. R is false because the tapetum nourishes the developing microspores (pollen grains), not the microspore mother cells. Answer (3), as in the answer key.
