Double Fertilization: The process of fusion of male gamete with the female gamete to form a diploid zygote (2n) is called fertilization. ... One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing the syngamy. This results in the formation of a diploid cell, the zygote.
