Question

Double fertilization 12 hsc

Answer 1

double fertilization is a complex fertilization mechanism of flowering plants.this process involves the joining of a female gametophyte with two male gemetes .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 ovule.the pollen tube proceeds to release the two sperm in the magagametopyte.
