The genetic makeup of endosperm is 3 n.

Angiosperms have a double fertilization process. Syngamy is the process by which a single male gamete joins an egg to create a zygote. A triploid primary endosperm nucleus, also known as a PEN, is created when the other male gamete fuses with the two polar nuclei in the central cell. Triple fusion is the name of this procedure. Double fertilization refers to the fact that fertilization takes place twice. The stimulation from the second fertilization helps the plant grow as the ovary transforms into a fruit. A diploid zygote is created when male and female haploid gametes combine. A new plant is created as a result of the zygote developing into an embryo.
