Given below are two statements : one is labelled asAssertion (A) and the other is labelled as Reason(R).Assertion (A): Cells of the tapetum possess densecytoplasm and generally have more than onenucleus.Reason (R): Presence of more than one nucleus inthe tapetum increases the efficiency of nourishingthe developing microspore mother cells.In the light of the above statements, choose the mostappropriate answer from the options given below:
Answer
Assertion and Reason Explanation
Assertion (A):Cells of the tapetum possess dense cytoplasm and generally have more than one nucleus.
✅ This statement is true. Tapetal cells are metabolically active and multinucleate, which supports their role in nutrient supply.
Reason (R):Presence of more than one nucleus in the tapetum increases the efficiency of nourishing the developing microspore mother cells.
❌ This statement is false. While the tapetum does nourish developing pollen grains (microspores), the reason provided is inaccurate. It is not the presence of multiple nuclei specifically that enhances nourishment, but rather the general secretory and nutritive nature of the tapetum itself.
Conclusion:A is true, but R is false.
✔ Correct Answer: (3) A is true but R is false.
