Double fertilisation is an unique event to angiosperms. Explain the event and its possible significance.

Answer

Double fertilisation is unique to angiosperms:

In this phenomenon, two male gametes are discharged by a pollen tube into the embryo sac of an ovule.
One male gamete fuses with the female gamete to form a zygote; this fusion is called syngamy.
A second male gamete fuses with the secondary nucleus to form the primary endosperm nucleus; this is called triple fusion.
