• It includes all the flowering plants.

• Classes: Monocotyledon and Dicotyledon

• It maybe a bisexual flower or unisexual flower.

• One male gamete will fuse with egg cell and form zygote.

• 2n = n + n (Syngamy).

• Another male gamete will fuse with polar nuclei and will form endosperm. [3n = Triple fusion]

• The main function of endosperm is to provide nourishment to the developing zygote. That's why zygote is not formed before endosperm fertilization is taking place two time known as double fertilization.
