Double fertilization occurs when 1 of these sperm combines with theegg, and the other sperm combines with a cell (this is called endosperm) That is in order for the seed to keep being produced.Seed has to be germinated, and without the extra sperm (double fertilization) the plant couldn't germinate and would go extinct.
