Question

Female gametophyte of angiosperms is represented by:
A. Ovule
B. Megaspore mother call
C. Embryo sac
D. Nucleus

Answer 1

Plants go through a rotation of generation life cycle that includes a multicellular haploid generation, called the gametophyte, and a multicellular diploid generation, called the sporophyte.

Complete Answer:
- Sexual reproduction in plants is started with sporogenesis, during which specific cells (mother cells) inside the sporophyte go through meiosis and offer ascent to haploid spores. Spores go through gametogenesis, a cycle of cell proliferation and differentiation, to develop into multicellular gametophytes, which at that point produce the gametes (sperm and egg cells). Fusion of egg and sperm to shape the zygote, trailed by embryo body plan development gives rise to the sporophyte, subsequently finishing the life cycle.
- The angiosperm gametophytes are made out of a couple of cells and are implanted inside the sexual organs of the flower. The female gametophyte develops inside the ovule and for the most part comprises three antipodal cells, one central cell, two synergid cells, and one egg cell. The female gametophyte is additionally usually called the embryo sac or megagametophyte. The male gametophyte, additionally called the pollen grain or microgametophyte, creates inside the anther and comprises two sperm cells encased inside a vegetative cell.
- The angiosperm female gametophyte is critical for plant reproduction. It contains the egg cell and central cell that become fertilized and give rise to the embryo and endosperm of the seed, individually. Female gametophyte advancement starts right off in ovule development with the formation of a diploid megaspore mother cell that goes through meiosis.

Henceforth, the right answer is C, i.e. Embryo sac.

Note: Female gametophyte formation is needed for sexual and asexual seed development in angiosperms. In sexual reproduction angiosperms, seed development starts when pollen is transferred from the anther to the carpel's stigma.
