Question

Write four points of difference between pollination and fertilization

Answer 1

Pollination and fertilization are different through the fact that pollination leads to fertilization. Pollination is just the process of transferring the pollen to the stigma. This can be done through either self pollination, or cross pollination. Cross pollination is when there are outside agents, like animals, people or the wind, to facilitate the transfer of pollen to stigma. While pollination also only applies to flowering plants, as they are the only ones producing pollen. Fertilization applies to almost everyone in nature and there can be no fertilization if there is no pollination.

Pollination and fertilization are two natural acts in the plant and in the animal kingdom. Just keep in mind that pollination will lead to fertilization and fertilization does not only apply to plants alone.

Pollination :

(i) It is the transfer of pollen grains from the anther to the stigma of a flower.
(ii) It is achieved by agents like wind,water or animals.
(iii) It leads to fertilization.
(iv) It is an external process.

Fertilization :

(i) It is the fusion of male gamete with female gamete (egg).
(ii) It is achieved by the growth of pollen tube so that the male gamete reaches the female-germ" cells.
(iii) It leads to formation of seeds.
(iv) It is an internal process.
