Question

Assertion (A): Perisperm is a diploid tissue.

Reason (R): Perisperm is the remains of nucellus which surrounds the embryo in certain seeds.

Options

• Both (A) and (R) are true and (R) is the correct explanation of (A).

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

• (A) is true, but (R) is false.

• (A) is false, but (R) is true.

Answer 1

Both (A) and (R) are true, but (R) is not the correct explanation of (A).

Explanation:

As perisperm comes from the nucellus, a diploid maternal tissue, it is, in fact, diploid. During embryonic development, the nucellus is depleted; nevertheless, in certain instances, it endures, which is unrelated to its ploidy.
