AP BIOLOGY

Detailed explanation-1: -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-2: -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-3: -How does pollen get from one flower to another? Flowers must rely on vectors to move pollen. These vectors can include wind, water, birds, insects, butterflies, bats, and other animals that visit flowers. We call animals or insects that transfer pollen from plant to plant “pollinators”.

Detailed explanation-4: -Pollination is the transfer of pollen from an anther of a plant to the stigma of a plant, later enabling fertilisation and the production of seeds, most often by an animal or by wind.

Detailed explanation-5: -Flowers produce a sugary liquid called nectar which many insects consume on a large basis. When insects land on a flower, pollen grains tend to stick to their bodies. The insect then moves from one to another flower of the same species, pollen gets transferred to the stigma of flowers and hence causing pollination.
