Question

Assertion: Megaspore mother cell undergoes meiosis to produce four megaspores.

Reason: Megaspore mother cells and megaspores both are haploid.

• A. Both assertion and reason are false.
• B. Both assertion and reason are true, and reason is the correct explanation for assertion.
• C. Both assertion and reason are correct, but reason is not the explanation for assertion.
• D. Assertion is true, and reason is false.

Answer 1

The correct option is D

Assertion is true, and reason is false.

The correct option is D.

Assertion statement:

1. Megaspores are produced by meiosis or reduction division in the megaspore mother cell.
2. Meiosis in megaspore mother cell gives rise to four haploid megaspores.

Reason statement:

1. The megaspore mother cell is a large diploid cell (2n) with a prominent nucleus and dense cytoplasm.
2. The megaspore formed as a result of reductional division is haploid (n).

Final answer:(D) Assertion is true, and the reason is false.
