Double Fertilisation

> It is mechanism of fertilization seen in flowering plants in which fertilisation occurs twice.

> It includes 2 male gametes and 1 female gamete.

> The process of syngamy together with triple fusion is called Double Fertilisation.

> One male gamete fuses with female gamete to form an embryo (syngamy) while another male gamete fuses with polar nuclei (triple fusion) to form endosperm.

> It produces one diploid cell (zygote) and one triploid cell.
