Question

Considering the cell distribution in a mature embryo sac, how many haploid cells are present in total?

Options

• 8 haploid cells

• 7 haploid cells

• 6 haploid cells

• 5 haploid cells

Answer 1

In the mature embryo sac, the haploid cells are: one egg cell, two synergids, and three antipodal cells, totaling 6 haploid cells. The two polar nuclei in the central cell are also haploid individually but fuse to form a diploid nucleus, and they are not counted as separate cells since they remain in the shared central cell.
