Female gametophyte in angiosperm is also known as :

Embryo Sac

The correct answer is Option (2) –Embryo Sac

The female gametophyte in angiosperms is also known as the "Embryo Sac." The embryo sac is the structure within the ovule of a flowering plant (angiosperm) where the female gametes, including the egg cell, are located. It is the female reproductive structure that plays a crucial role in fertilization and seed development.

There is a characteristic distribution of the cells within the embryo sac. Three cells are grouped together at the micropylar end and constitute the egg apparatus. The egg apparatus, in turn, consists of two synergies and one egg cell. The synergids have special cellular thickenings at the micropylar tip called filiform apparatus, which play an important role in guiding the pollen tubes into the synergid. Three cells are at the chalazal end and are called the antipodals. The large central cell, as mentioned earlier, has two polar nuclei. Thus, a typical angiosperm embryo sac, at maturity, though 8-nucleate is 7-celled.
