One fuses with the egg cell to form a zygote,and the other fuses with the polar nuclei to form the primary endosperm nucleus.

Vedclass · Answer

(A) In angiosperms,each pollen grain produces two male gametes.$1$. The first male gamete fuses with the egg cell (syngamy) to form a diploid zygote $(2n)$,which eventually develops into an embryo.$2$. The second male gamete fuses with the two polar nuclei (or the secondary nucleus) in the central cell to form the primary endosperm nucleus $(PEN)$,which is triploid $(3n)$. This process is known as triple fusion.Together,syngamy and triple fusion constitute the process of double fertilization.
