Bee and flower, computer artwork. The bee is using its wings to hover next to a flower (left). It will use its proboscis to drink nectar from the flower. In reaching the source of the nectar, it will make contact with the anthers (stalked structures at the centre of the flower) and pollen grains will be transferred from the flower to the bee. As the bee visits different flowers, the pollen will be transferred between them. This process, called cross-pollination, is how many flowering plants reproduce. Bees are insects in the superfamily Apoidea, and are closely related to ants and wasps.
