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 light of the above statements, choose the most appropriate answer from the options given below :

1. Both A and R are true and R is the correct explanation of A

2. Both A and R are true but R is not the correct explanation of A

3. A is true but R is false

4. A is false but R is true

Best answer

Answer: 1. Both A and R are true and R is the correct explanation of A

Key idea: The tapetum is the innermost wall layer of the anther and nourishes the developing pollen.

A is true: tapetal cells have dense cytoplasm and are often multinucleate. R is true: more nuclei mean more active synthesis, so nourishing the microspore mother cells is more efficient. R explains A. Option 1.
