Question

Fertilisation in angiosperms is knoqn as double fertilisation.give reasons

Answer 1

Angiosperms, or flowering plants, undergo a unique process called double fertilization. After pollination brings a pollen grain to a flower's female reproductive structure (carpel), a pollen tube releases two sperm cells. ... The second sperm cell fuses with two polar nuclei, creating a triploid endosperm.

Answer 2

Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm. Together, these two fertilization events in angiosperms are known as double fertilization.
