Angiosperms undergo two fertilization events where a zygote and endosperm are both formed.
Together, these two fertilization events in angiosperms are known as double fertilization .
After fertilization is complete, no other sperm can enter.
After fertilization, embryonic development begins.
This is called a double fertilization.
In angiosperms, the process of seed development begins with double fertilization and involves the fusion of the egg and sperm nuclei into a zygote.
In gymnosperms, the two sperm cells transferred from the pollen do not develop seed by double fertilization, but one sperm nucleus unites with the egg nucleus and the other sperm is not used.
Sometimes each sperm fertilizes an egg cell and one zygote is then aborted or absorbed during early development.
The ovules after fertilization develop into the seeds.
In non-endospermic dicots, the triploid endosperm develops normally following double fertilization, but the endosperm food reserves are quickly remobilized, moving into the developing cotyledon for storage.
