Question

Why fusion of male nucleus with the secondary nucleus of embryo sac is called fertilization?

Answer 1

Answer:

All angiosperms are characterized by a unique process called double fertilization. Double fertilization involves two sperm cells; one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit. So, it is called double fertlisation.
