Question

Describe the development of female gametophyte in Angiosperms.​

Answer 1

Spores undergo cell proliferation and differentiation to develop into gametophytes. The major function of gametophyte generation is to produce haploid gametes. ... The female gametophyte, also referred to as the embryo sac or megagametophyte, develops within the ovule, which is found within the carpel's ovary.

Answer 2

Monosporic development is the development of female gametophyte from one functional megaspore. In angiosperms, a single diploid mother megaspore undergoes meiotic division to form four megaspores (haploid). Only one out of the four megaspores is functional that forms a female gametophyte, while the rest of the three degenerate.
