Question

Quizplus · Accepted Answer

Double fertilization is a process unique to angiosperms in which one sperm cell fuses with the egg to form a zygote, while the other sperm cell fuses with two polar nuclei to form a triploid endosperm. This endosperm will serve as a source of nutrients for the developing embryo. Single fertilization is a common process in other seed plants, where only one sperm cell fuses with the egg to form a zygote. Syngamy is a general term for the fusion of gametes, which occurs in all sexually reproducing organisms. Alternation of generation is a life cycle pattern found in some plants and algae, but is not unique to angiosperms. Seed production is a common feature of all seed plants, but is not unique to angiosperms.
