Doubl fertilisation and its importance in plant life

Answer 1

the fertilization process characteristic of flowering plants, in which one sperm cell of a pollen grain fertilizes an egg cell while a second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm.
advantage:-
since it involves the use of both male and female gametes produced by a pollen grain, hence it increases the chances of survival of the plant. also the possibility of embroyology increases..
