Vegetative fertilization is the formation of a triploid primary endosperm

nucleus (PEN) by fusing the second male gamete with the two polar nuclei

present in the central cell of the central cell. The embryo sac is where this process

occurs. The micropylar end of the pollen tube enters the embryo sac after reaching

the ovary. Once the pollen tube has penetrated, its tip ruptures, releasing two male

gametes. To form the diploid zygote, the one male gamete fuses with the egg.

Trichotomy is the method of creating a triploid endosperm by combining the two
