What process results in the formation of the endosperm and the embryo in angiosperms?

The formation of the endosperm and the embryo in angiosperms results from the process of double fertilization. During this process, one sperm cell fertilizes the egg cell to form the diploid embryo, while another sperm cell fuses with two polar nuclei to form the triploid endosperm. This unique process ensures that the endosperm and embryo develop concurrently, with the endosperm providing the necessary nutrients to support the embryo’s growth and development. Double fertilization is a distinctive feature of angiosperms that enhances seed development and survival.
