Answer 1

Answer:

C. S.G. Nawaschin

Double fertilization was discovered independently by Sergei Nawaschin and Léon Guignard in 1898. Double fertilization is a unique feature of angiosperms, or flowering plants. It occurs when one sperm fuses with the egg cell to form the embryo, and the other sperm fuses with the polar fusion nucleus to form the endosperm. The endosperm provides food for the embryo.
