Together, these two fertilizationevents in angiosperms are known as double fertilization. ... Double fertilization: In angiosperms, one sperm fertilizes the egg to form the 2n zygote, while the other sperm fuses with two polar nuclei to form the 3n endosperm. This is called a double fertilization.

Fertilization:

1. It is the union of two compatible gametes.

2. It occurs in almost all eukaryotes.

3. Fertilization produces a diploid zygote.

Double Fertilization:

1. It is union of one male gamete with egg and the other male gamete with secondary nucleus of the same embryo sac.

2. It is restricted to angiosperms only.

3. Double fertilization produces a diploid zygote and a triploid primary endosperm cell.
