As the bee is obtaining food, pollen from the plant's male component, the anther, rubs off and sticks to the bee's body. The bee flies to a similar flower to gather more nectar, and some of the tag-along pollen is shed on this plant's female part, the stigma. This fertilizes the plant and allows it to reproduce. Honey bees are particularly good partners for mutualism because they specifically search for plants with pollen. The bees need this powder to feed their larvae.
