Question

Formation of primary endosperm nucleus is called triple fusion. Give reason.

Answer 1

The haploid sperm and haploid egg combine to form a diploid zygote, while the other sperm and the two haploid polar nuclei of the large central cell of the megagametophyte form a triploid nucleus. It will later develop into the endosperm, nutrient tissue which provides nourishment to the developing embryo.
