what is double fertilisation and triple fusion
Answers
In angiosperms, double fertilisation refers to the fusion of one sperm cell with an egg (syngamy), and another sperm cell with the polar nuclei to yield a triploid endosperm (triple fusion). Double fertilisation involves two processes, triple fusion and syngamy.
Answer:
Double Fertilization
The process in which the two sperm nuclei of a pollen grains unite with the nuclei of the embryo sacof an angiosperm plant Together these nuclei form the triploid nucleus of the cell from which the endosperm develops. Double Fertilization in this form is unique to the angiosperms .

TRIPLE FUSION
Triple fusion is the fusion of mate gametes with two polar nuclei inside the embryo sac in the angiosperm .. Since this fusion involves the fusion of three haploid nuclei , it is known as triple fusion . It results in the formation of the endosperm.
