Question

The male gametophyte of an angiosperm consists of ______.

विकल्प

• an anther

• a sac containing eight haploid nuclei

• a microspore

• a germinated pollen grain

Answer 1

The male gametophyte of an angiosperm consists of a germinated pollen grain.

Explanation:

The male gametophyte of an angiosperm is a 3-celled structure that develops from a microspore (pollen grain) and consists of two male gametes and a tube cell. When the pollen grain germinates, it forms the male gametophyte capable of fertilization. This structure is distinct from the anther, microspore, or the sac containing eight haploid nuclei (which is the female gametophyte or embryo sac).
