Explain the event of double fertilization in angiosperms.

Double fertilization is a unique process in angiosperms where one sperm nucleus fuses with the egg cell to form a diploid zygote, while the other sperm nucleus fuses with two polar nuclei to form a triploid endosperm. This endosperm provides nourishment to the developing embryo.
