Caption: Animation of airborne pollen grains from eight different plant species. Airborne pollen is a common cause of hay fever, or allergic rhinitis. It is typically caused by wind-pollinated plants, particularly trees and grasses. Pollen contains the male sex cells of a flowering plant, and is dispersed by wind or animals to find a female flower.
