The female gametophyteâspecifically termed a megagametophyte âis also called the embryo sac in angiosperms. The megagametophyte produces an egg cell (or several egg cells in some groups) for the purpose of fertilization.he ovary of the gynoecium produces one or more ovules and ultimately becomes the fruit wall. Ovules are attached to the placenta in the ovary through a stalk-like structure known as a funiculus (plural, funiculi). Different patterns of ovule attachment, or placentation, can be found among plant species, these include:
1 The female gametophyte remains inside the female megasporangium, which is surrounded by sporophyte integuments. 2  This structure is known as an ovule. 3  Eventually, after the ovum is fertilized and becomes a zygote, the ovule will become a seed.4  The outer covering, the seed coat is derived from sporophyte tissue.he Gametophyte of the Anthophyte. You saw the cherry tree above. To see the gametophytes, we need to examine that structure unique to the Anthophytes, the flower. 1  The microsporophylls are the stamens, each tipped by the anther, which contains the diploid cells that will divide to become microspores.
