Give the significance of double fertilization.

Answer 1

1. It is a unique feature of angiosperms.
2. It ensures that the parent plant invests a seed with a food store only if the egg is fertilized.
3. The diploid zygote develops into an embryo, which consequently develops into a new plant.
4. The triploid PEN develops into nutritive endosperm tissue.
5. It restores the diploid condition by the fusion of the haploid male gamete with the haploid female gamete (i.e., through syngamy).
6. It also helps to avoid polyembryony.
