Fertilization

Fertilization :  The fusion of male and female sex cells is called Fertilization. When pollen grains fall on the stigma, they move down through the tube called style and reach the ovary. In the ovary, the male sex cells present in the pollen grains fuse with the female sex cells present in the ovules. After, fertilsation, the ovules grow and become seeds. The ovary of a flower grows and becomes fruit. The fruit protect the seeds. The other parts of the flower dry up and fall off.

 Under suitable conditions i.e. availability of water, air and warmth, a seed germinates to become a baby plant.
