Question

what is double fertilization ​

Answer 1

Answer:

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.

Answer 2

Explanation:

Double fertilization is a complex fertilization mechanism of flowering plants. This process involves joining of a female gametophyte with two male gametes. It begins when a pollen grain adheres to the stigma of the carpel, the female reproductive structure of a flower.
