Question

explain double fertilization
​

Answer 1

Double fertilization is the fertilization process characteristic of flowering plants, in which one sperm cell of a pollen grain fertilizes an egg cell while a second fuses with two polar nuclei to produce a triploid body that gives rise to the endosperm.

Answer 2

Hii dear here is your answer

Double fertilization is a complex fertilizationmechanism of flowering plants (angiosperms). This process involves joining of a female gametophyte (megagametophyte, also called the embryo sac) with two male gametes (sperm). It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower. The pollen grain then takes in moisture and begins to germinate, forming a pollen tube that extends down toward the ovary through the style. The tip of the pollen tube then enters the ovary and penetrates through the micropyle opening in the ovary. The pollen tube proceeds to release the two sperm in the megagametophyte.
