WebDouble fertilization is a phenomenon unique to angiosperms. Each pollen grain produces two sperm; one fuses with an egg to form the zygote, and the other fuses with one or more polar nuclei in the female gametophyte (megagametophyte, or also “embryo sac”) to form an endosperm , which has a ploidy level that varies from 2 n to 15 n . WebNov 9, 2024 · These twin fertilization events occurring in angiosperms or flowering plants are termed double fertilization. Once the fertilization process is over, an additional sperm can't enter.
