Difference Between Pollination and Fertilization
|
Characteristics |
Pollination |
Fertilization |
|---|---|---|
|
Definition |
Transfer of pollen grains to the female organ |
Fusion of male and female gametes |
|
Main Process |
Pollen transfer |
Gamete fusion |
|
Objective |
Deliver pollen to female reproductive organs. |
Form a zygote and initiate seed development. |
|
Involves |
Male reproductive organ (anther) and pollen |
Male and female gametes |
|
Occurs in |
Angiosperms and gymnosperms |
Angiosperms and gymnosperms |
|
Mechanisms |
Wind, water, insects, birds, or other animals |
Pollen tube growth or direct pollen-ovule contact |
|
Self-pollination |
Transfer of pollen within the same flower or between flowers of the same plant |
Fusion of gametes from different flowers or plants |
|
Cross-pollination |
Transfer of pollen between flowers of different plants of the same species |
Ensures genetic diversity by mixing different genetic materials. |
|
Key Players |
Pollinators (insects, birds, etc.) |
Male and female gametes (sperm and egg) |
|
Result |
Pollen reaches female reproductive organs. |
Formation of a zygote and development of a seed |
Difference Between Pollination and Fertilization
Difference Between Pollination and Fertilization: Pollination is the transfer of pollen grains from the male reproductive organ (anther) to the female reproductive organ (stigma) in a flower resulting in the formation of seeds. It is primarily carried out by various agents like wind, water, insects, birds, or other animals.
