Which of the following structures give rise to the female gametophyte ...
Explanation:
The female gametophyte in angiosperms is formed from the megaspore mother cell (MMC) within the nucellus of the ovule. The process of female gametophyte formation involves several steps.
Formation of Female Gametophyte:
- **Megaspore Mother Cell (MMC):** The process begins with the formation of the megaspore mother cell within the nucellus.
- **Megaspore Formation:** The megaspore mother cell undergoes meiosis to produce four haploid megaspores. One of these megaspores undergoes further development while the others degenerate.
- **Female Gametophyte Development:** The surviving megaspore undergoes several rounds of mitotic divisions to produce the female gametophyte. This female gametophyte contains the egg cell, central cell, and synergids, which are essential for fertilization.
- **Maturation:** The female gametophyte matures within the ovule and is eventually ready for fertilization by the male gametophyte (pollen).
By the end of this process, the female gametophyte is fully developed and ready to receive the male gametophyte for fertilization. The nucellus and the megaspore mother cell play crucial roles in the formation and development of the female gametophyte in angiosperms.

Which of the following structures give rise to the female gametophyte ...
Nucellus and MMC are diploids. Cells of nucellus are somatic cells. Thus, diploid number of chromosomes is present. MMC is diploid and divides to produce haploid megaspores.
