Question

What role do bees and insects play in pollination?

Answer 1

Pollen grains have no way to move by themselves; they must depend on an outside source for help. A few flowers use wind or water to transfer pollen, but most depend on pollinator animals such as birds and insects to assist in the process.
Insects typically pollinate flowers as they move from plant to plant searching for food. Many flowers produce nectar, a sugary liquid that many insects eat. When an insect lands on a flower to feed, pollen grains stick to its body. As the insect moves to another flower of the same species, these pollen grains are transferred to the flower’s stigma and pollination occurs. Perhaps the most well-known pollinator insects are bees and butterflies, but wasps, moths, flies and beetles can be pollinators as well.
