Question: Describe the process of double fertilization?

Double fertilization is a unique process of sexual reproduction in flowering plants or angiosperms. It involves the fusion of two male gametes (sperm cells) from a pollen grain with two different female gametes (egg cell and polar nuclei) in the embryo sac of an ovule. One sperm cell fertilizes the egg cell, forming a diploid zygote that develops into an embryo. The other sperm cell fuses with the two polar nuclei, forming a triploid nucleus that develops into an endosperm, which provides nourishment to the embryo. Double fertilization ensures that the seed contains both an embryo and a food supply, and also stimulates the development of the ovary into a fruit.
