Question

Which is the correct order of events for female gametophytes?
A. Megagametophyte; megasporocyte; megaspore
B. Megagametophyte; megaspore; megasporocyte
C. Megasporocyte; megaspore; megagametophyte
D. Megaspore; megasporocyte; megagametophyte

Answer 1

The female gametophyte is made up of three antipodal cells, one central cell, two synergid cells, and one egg cell that grows within the ovule. The female gametophyte is also known as the megagametophyte or embryo sac.

Complete answer:
In angiosperms, female gametophyte creation is essential for both sexual and asexual seed development. Seed development in sexually reproducing angiosperms occurs when pollen is transported from the anther to the stigma of the carpel.
The female gametophyte, also known as the megagametophyte or embryo sac, develops within the ovule, which is lodged within the ovary of the carpel. The female gametophyte is a type of angiosperm that comes in a range of shapes and sizes.
The megaspore mother cell is the megasporocyte. Meiotic division happens in a diploid cell. The creation of four haploid megaspores occurs during meiosis in a megasporocyte. The gametophyte or megagametophyte grows from one of these megaspores.

Hence correct option is C. Megasporocyte; megaspore; megagametophyte

Note:
The pollen tube is guided to the embryo sac by peptides secreted by the adult female gametophyte, which also contains protein complexes that limit seed formation before fertilization.
Not only does the female gametophyte produce female gametes, but it also supplies the physical and molecular foundation for fertilization and seed formation. As a result, this tiny structure serves as the primary focus of plant reproduction.
