Detailed explanation-1: -Pollination is simply the transfer of pollen grains from an anther to a stigma. Fertilization occurs much later when the pollen grains germinate on the stigma and send down a pollen tube which releases the sex cells to fertilize the ovules.

Detailed explanation-2: -The transfer of pollen grains from the anther to stigma of a flower is called pollination.

Detailed explanation-3: -In plants, fertilization is a process of sexual reproduction, which occurs after pollination and germination. Fertilization can be defined as the fusion of the male gametes (pollen) with the female gametes (ovum) to form a diploid zygote. It is a physicochemical process which occurs after the pollination of the carpel.

Detailed explanation-4: -After the pollen lands on a suitable stigma, it has to reach the female germ-cells. which are in the ovary.then, a tube grows out of the pollen grain and travels. through the style to reach the ovary. this is how stigma play a role in the process of fertilization.

Detailed explanation-5: -When the sperm cell from the pollen grain reaches the ovary or ovule the sperm joins with the egg. This is called fertilization.
