Differences between pollination and fertilization

Pollination	Fertilization
It occurs outside the plants	It occurs inside the plants
Pollen grains in the anther reaches the stigma of the ovary	Sperm and ovum combine to form zygote
Physical agents like wind, water, and insects help in this process.	No agents are required for this process.
It leads to fertilization	It leads to formation of zygote
It occurs in flowering plants	It occurs in plants and animals
It occurs before fertilization	It takes place after pollination

Pollination

It is the process by which pollen grains present in the anther transfer into the stigma. Wind, insects, and water are the physical agents that help in pollination.

Pollination is of two types:

Self pollination
Cross pollination

Self pollination

When transfer of pollen grains from anther to stigma occurs in the same plant, then it is called self pollination.

Cross pollination

Cross pollination occurs when pollen grains are transferred from the anther of one plant to the stigma of another plant.

Fertilization

In this process, the fusion of sperm and ovum results in the formation of a zygote. This process occurs after pollination in plants and does not require any agents.
