Answer 1

Answer:

It is a process involved in the sexual reproduction of angiosperms. Triple fusion is a fusion that involves a sperm nucleus and two polar nuclei which occurs in the double fertilization in a seed-bearing plant that results in the endosperm formation. The fusion process occurs in the embryo sac of the angiosperms. In the event of fertilization, when the stigma comes in contact with the pollen grains, it germinates, giving rise to the pollen tube which enters the ovule through the style.
