Question

Describe the development of female gametophyte in Angiosperms.

Answer 1

Spores undergo cell proliferation and differentiation to develop intogametophytes. The major function ofgametophyte 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

Explanation:

• The process by which the 'megaspore mother cell' converted into the megaspore is called the megasporogenesis. The 'megaspore mother cell' contains a nucleus and a dense cytoplasm.
• This megaspore mother cell produces four megaspores, under which only one 'megaspore is functional' and the other three remains degenerate. The nuclei of the functional megaspore divided mitotically into 2 nuclei and goes to the opposite ends.
• Another two mitotic cell divisions happens to form '4 nucleate' and '8 nucleate embryo sac'. After the completion of the '8 nucleate stage' , the cell walls are arranged and the female gametophyte formed.
