DOUBLE FERTILIZATION. “As implied by the name, the gametophyte generates the gametes, two sperms in the male pollen and a single egg in the female embryo sac.” Both sperms are used in a double fertilization event — one for the egg cell (to make a diploid zygote) — and the other for the megamametophyte (to make a triploid nucleus of the endosperm). Wow.
