Answer 2

Answer:

1. The process of double fertilization occurs inside each embryo sac in which two fusions, i. e., syngamy and triple fusion take place.
2. As the pollen tube enters the ovule, the pollen tube releases two male gametes into embryo sac.
3. The embryo sac contains the egg.
4. The fusion of male and female gametes in the embryo sac of ovule is called syngamy. The product is called zygote.
5. The other male gamete fuses with the two polar nuclei. It is called triple fusion.
