Lots of plants produce pollen as a way to reproduce. In order for seeds to be produced, the pollen must be transferred from the male part of the flower to the female part of the flower.
Some plants called entimophilousdisperse their pollen from plant to plant with the help of birds and bees. They tend to have large, showy, and brightly-colored flowers, to attract pollinators.
Other plants called anemophilous disperse their pollen with the help of the wind. It is the wind-pollinated plants that usually cause allergies. The flowers of these plants tend to be small and the pollen very lightweight.
