6 Name the products obtained as a
result of these fusions.​

Answer 1

The pollen grain has two male gametes. One of the male gamete fuses with the female gamete in the ovule and the other one fuses with the polar nuclei. This event is called double fertilisation.

The first fusion results in the formation of a zygote, whereas the other one results in the formation of endosperm.

Answer 2

Answer:

a) During the double-fertilization event, one sperm cell fuses with the egg cell, forming the embryo, and a second sperm cell fertilizes the central cell, which develops into the endosperm.

b) Double fertilization involves two sperm cells; one fertilizes the egg cell to form the zygote, while the other fuses with the two polar nuclei that form the endosperm. After fertilization, the fertilized ovule forms the seed while the tissues of the ovary become the fruit.
