Describe double fertilization in plants
WebDouble fertilization in plants is the fusion of two sperm cells with an egg cell (resulting in a zygote) and two polar nuclei (resulting in the endosperm), respectively. Double … WebIn angiosperms, double fertilization generates the embryo and the endosperm simultaneously, the joint development of which leads to a viable seed. Somatic embryos, however, are formed from plant cells that are not normally involved in the development of embryos (fertilization or gamete fusion).
