Detailed explanation-1: -Pollen, which contains a lot of protein and is primarily used to rear the brood, is picked up by the bees almost as they fly past. It sticks to the hairs on the bees, and when they visit the next plant of the same species it is transferred in adequate quantities to their stigma.

Detailed explanation-2: -When a bee lands on a flower, the hairs all over the bees’ body attract pollen grains through electrostatic forces. Stiff hairs on their legs enable them to groom the pollen into specialized brushes or pockets on their legs or body, and then carry it back to their nest.

Detailed explanation-3: -Pollination is the process by which tiny little grains of pollen are transferred from the flower of one plant to the flower of another plant. Pollen fertilizes the plant allowing it to develop seeds and produce fruit.

Detailed explanation-4: -“When a bee visits the first flower on a plant, 80 percent of the resulting seeds are cross-pollinated, ” Karron says. “By the time it alights on the fourth flower of that plant, almost all the seeds are self-pollinated.”

Detailed explanation-5: -Pollination by insects is called entomophily. Entomophily is a form of pollination whereby pollen is distributed by insects, particularly bees, Lepidoptera (e.g. butterflies and moths), flies and beetles.
