Question

how many cells are there in mature embryo sac?​

Answer 1

The mature embryo sac consists of four cell types; the egg cell and the two synergids at the micropylar end, the antipodals at the chalazal end and the central cell containing the two polar nuclei and a large central vacuole (B).

Answer 2

Answer:

seven cells

Explanation:

In total, the embryo sac is composed of seven cells each of which probably has a precise role during the fertilization process. At the micropylar end, two synergids are generally found, one on each side of the egg cell, although there are exceptions (e.g. no synergids in Plumbago zeylanica) (Russell, 1992).
