Question

development of female gametophyte in angiosperm is monosporic and endosporic. give reason.​

Answer 1

Answer:

The female gametophyte or the embryo sac develops from a single functional megaspore. This is known as monosporic development of the female gametophyte. ... Later, out of these four megaspores, only one functional megaspore develops into the female gametophyte, while the remaining three degenerate.

Explanation:

Answer 2

Answer:

• Female gametophyte (embryo sac) in most of the angiosperms develops from a single megaspore. The megaspore mother cell divides by meiotic division to give rise to 4 haploid megaspores, of which one develops into the female gametophyte and the rest of the three degenerate. This is known as monosporic development.

Explanation:

• When the female gametophyte (embryo sac) develops from a single megaspore, it is called monosporic development. Usually, in most angiosperms, the megaspore mother cell divides by meiosis to form four haploid megaspores arranged in a linear fashion.
