Question: Which of the following is the first cell of the female gametophyte generation in angiosperms?
A Zygote
B Egg cell
C Functional megaspore
D Embryo sac
Answer: Functional megaspore
| Cells of female gametophyte generation | Description | |
| 1 | Functional Megaspore | · The first cell of the female gametophyte generation in angiosperms.
· It develops into the female gametophyte. |
| 2 | Mitotic Division 1 | · The functional megaspore undergoes a mitotic division to form two nuclei. |
| 3 | Mitotic Division 2 | · One of the nuclei moves to the other side of the cell, resulting in two nuclei separated by a large central vacuole. |
| 4 | Mitotic Division 3 | · Each of the two nuclei divides, yielding a total of four nuclei in the cell. |
| 5 | Female Gametophyte | · The cell contains the four nuclei two polar nuclei and two synergids. |
| 6 | Egg Cell | · One of the nuclei in the female gametophyte becomes the egg cell, the female gamete involved in fertilization. |
| 7 | Central Cell | · The other three nuclei in the female gametophyte form the central cell, which fuses with a sperm cell during fertilization. |
| 8 | Synergid Cells | · These cells have a role in guiding pollen tubes during fertilization. |
| 9 | Antipodal Cells | · These cells are often found at the opposite end of the female gametophyte and their exact function is less clear, but they may be involved in nourishment and support. |
