False

Fertilisation in angiosperms involves two important steps called syngamy and triple fusion. Syngamy is an event of actual fertilisation of sperm and egg in the embryo sac. Triple fusion is a characteristic event in angiosperms where out of two sperms one fuses with the primary endosperm nucleus to form the endosperm which nourishes the zygote formed by syngamy.
