8. Reproduction in Plants

Fertilization in plants:

This is the second step in the process of sexual reproduction.

Definition:

The process of formation of zygote by fusion of male & female gametes is called as fertilization.

Process:

1. Anther contain pollen grains which produce male gametes i.e. sperm cells.
2. During pollination, the pollen grains reach the stigma of the flower. 
3. Then a pollen tube is formed which grows down the style to the ovary.
4. Male gametes (sperm cells) are released in the pollen tube which reach the ovule.
5. The ovule contains female gametes (egg cells).
6. The male & female gametes fuse together in the ovule to form zygote (fertilized egg).
7. This zygote develops into a embryo.

To remember:

1. Fertilization is the process of forming zygote.
2. The zygote develops into embryo of the seed.
