Fusion of a male gamete with an egg in the embryo sac is called
Autogamy
Syngamy
Triple fusion
Double fertilisation
One of the male gametes moves towards the egg cell and fuses with its nucleus thus completing syngamy.
Explain why sexual reproduction in angiosperms is said to take place through double fertilisation and triple fusion. Also draw a labelled diagram of embryo sac to explain the phenomena.
