Question

the number of cells present in a female gametophyte​

Answer 1

Answer:

Female gametophyte is a 7-celled and 8-nucleated structure.

There are 6 haploid cells and 2 polar nuclei (in the central cell).  

6 haploid cells include 3 haploid antipodal cells, 2 haploid synergids, and 1 egg cell.

The central cell includes 2 polar nuclei.

Egg cell and polar nuclei participate in double fertilization.

Answer 2

Answer:

There are usually eight (haploid) cells in the female gametophyte: a) one egg, two synergids flanking the egg (located at the micropyle end of the embryo sac); b) two polar nuclei in the center of the embryo sac; and three antipodal cells (at the opposite end of the embryo sac from the egg).
