Question

what is double fertilization

Answer 1

Answer:

Double fertilization is a complex fertilization mechanism of flowering plants (angiosperms). This process involves joining of a female gametophyte 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.

Double fertilization is the process in which one male gamate fuses with egg cell and another male gamate fusses with secondary nucleus, to form an embryo and endosperm respectively.
