Answer:
This is process in which the two sperm of a pollen nuclei grain unite with nuclei of the embryo sac of another angiosperm plant. sperm nucleus of singular number unites with the egg to produce diploid zygote, from which the embryo is generated.
The other sperm unites with the two nuclei located in a single cell at the center of the embryo sac.
Triploid nucleus of the cell is formed together with these nuclei in which the endosperm springs. Double fertilization in this form is unique to the angiosperms.
