Detailed explanation-1: -When the pollen of a flower lands on the stigma of another flower of the same plant, or that of different plant of the same kind, it is called cross pollination.

Detailed explanation-2: -Pollination : The mechanism of transferring pollen grains from the anther of one flower to the stigma of another flower of the same or different plant is called pollination.

Detailed explanation-3: -When the pollen is transferred from the anther of a flower to the stigma of the same flower or to the stigma of another flower of the same plant, it is called self pollination. Self pollination is also called autogamy.

Detailed explanation-4: -Entomophily is a type of cross-pollination in which the pollens from the anther of one plant are transferred to the stigma of another flower with the help of insects.

Detailed explanation-5: -If the pollen grain of one flower lands on the stigma of another and they are of different kinds, i.e.they belong to different species then cross-pollination won’t take place because the 2 flowers belong to different species. The pollen will fail to germinate and perish and no pollination will take place.
