DENDROLOGY

Detailed explanation-1: -Some creatures, such as honey bees, birds, wind, and water, can enhance pollen grain transfer, and they are called pollinating agents. Pollination is divided into two types: self pollination and cross pollination .

Detailed explanation-2: -Cross-pollination occurs when a bee collects pollen from one plant and transfers it to another. Cross-pollination occurs as a result of pollinators, such as insects and other animals, or as a result of wind blowing pollen from plant to plant.

Detailed explanation-3: -If the pollen lands on the stigma of the same flower or when the pollen of a flower lands on the stigma of another flower of the same plant it is called self-pollination. When pollen lands on the stigma of a different flower on another plant but of the same species, it is called cross-pollination.
