Upon penetrating the female gamertophyte, one sperm fertilizes the egg which then becomes the zygote. After fertilization, the ovule becomes the seed. A second sperm from the pollen grain combines with two or more other nuclei produced by the female gametophyte to form a polyploid endosperm nucleus that will divide to produce food for the devloping embryo.
