WebOne sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm, which serves as a source of nutrition for the developing embryo. Together, these two fertilization events in angiosperms are known as double fertilization, illustrated below. brett lindsay architect
