Detailed explanation-1: -double fertilization, in flowering plant reproduction, the fusion of the egg and sperm and the simultaneous fusion of a second sperm and two polar nuclei that ultimately results in the formation of the endosperm (the food-storage tissue) of the seed.

Detailed explanation-2: -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.

Detailed explanation-3: -Double fertilization is the process in which a diploid zygote and a triploid endosperm are formed. It is a characteristic found only in angiosperms.

Detailed explanation-4: -In angiosperms, double fertilization results in the production of an embryo and endosperm, both of which are critical for the development of viable seed. Diploid plants produce diploid embryos and triploid endosperm tissue.
