Question

explain double fertilization in plants ​

Answer 1

Double fertilization involves two steps :-

1. Syngamy

2. Triple fusion

Syngamy ⇒ During the fertilization in flowering plants pollen tube releases two male gametes & it moves towards the egg cell and fuses with the nucleus to form diploid zygote.

Triple fusion ⇒ The other male gametes move towards the two polar nuclei located in the central cell & fuses with it & produce triploid primary endosperm nucleus.

This is called double fertilization.
