Angiosperm Life cycle | Flowering Plant life cycle
The flower of the sporophyte produces microspores that form male gametophytes and megaspores that form female gametophytes.
The male gametophytes are in the pollen grains, which develop within microsporangia in the anthers. Each male gametophyte has two haploid cells: a generative cell that divides, forming two sperm, and a tube cell that produces a pollen tube. Each ovule, which develops in the ovary, contains a female gametophyte, also known as an embryo sac. The embryo sac consists of only a few cells, one of which is the egg.
After its release from the anther, the pollen is carried to the sticky stigma at the tip of a carpel. Although some flowers self-pollinate, most have mechanisms that ensure crosspollination, which in angiosperms is the transfer of pollen from an anther of a flower on one plant to the stigma of a flower on another plant of the same species.
After reaching the ovary, the pollen tube penetrates through the micropyle, a pore in the integuments of the ovule, and discharges two sperm cells into the female gametophyte (embryo sac). One sperm fertilizes the egg, forming a diploid zygote. The other sperm fuses with the two nuclei in the large central cell of the female gametophyte, producing a triploid cell (3n). This type of double fertilization, in which one fertilization event produces a zygote and the other produces a triploid cell, is unique to angiosperms.
After double fertilization, the ovule matures into a seed. The triploid central cell of the female gametophyte develops into endosperm, tissue rich in starch and other food reserves that nourish the developing embryo.
