Pollination of plants, or the transfer of pollen from one flower to another, is the most important role that bees play in the natural world. Bees are responsible for passing pollen from one flower to the next. In the course of doing their duties, they also harvest nectar. Bees don't have time to kick back and watch television when they get back to their hive because they're too busy making honey out of the nectar and pollen they collected on their way from one bloom to the next. Even queen bees contribute to the colony in some way.
