Question

can anybody please explain me the process of formation of female gametophyte

Answer 1

the female gametophytes (megagametophytes or embryo sacs) develop within the ovule There has been over a century of developmental studies on gametophyte development in a large number of diverse plant species In most flowering plants the embryo sac has a characteristic organization containing seven cells of four distinct cell types These four cell types are, first, the egg cell, which gives rise to the embryo, second, two accessory cells called synergid cells, which are important for pollen tube attraction, third, the central cell, which gives rise to the endosperm, and fourth, three cells of unknown function called antipodal cells. The entire embryo sac is enclosed within diploid sporophytic tissues called integuments, which will constitute the seed coat in the mature seed.
