Flowers need bees to help them complete the act of fertilization that allows them to reproduce, according to Michigan State University. As bees travel from flower to flower, pollen collected from one plant lands on another plant, pollinating it.
Pollination involves the movement of pollen from a plant's male components to its female components, inducing reproduction. Some plants require cross-pollination, a process in which pollen from one plant lands on another plant, to reproduce successfully.
Facilitation by Bees
Bees routinely collect pollen to carry back to their hives as a food supply for their young. As they travel from flower to flower, some of the pollen on the bees' bodies falls onto the flower, allowing the female parts of the flower to create new seeds.
To ensure that bees will visit and pollinate a flower, the flowering plants must attract the bee population in some way. One method involves the production of a sugary fluid called nectar, which bees consume for energy. The flowers' vivid colors or patterns also alert bees to the possible presence of nectar, according to the University of Arizona.
