Pollen is a fine powdery substance produced by the male parts of flowering plants, specifically the anthers of flowers. It consists of microscopic grains that contain the male gametes (sperm cells) of seed plants. Pollen is essential for plant reproduction, as it fertilizes the ovules in the female parts of flowers, leading to the production of seeds. The transfer of pollen from the male anther to the female stigma may occur through various means, including wind, water, or pollinators like insects, birds, and bats.
In addition to its role in plant reproduction, pollen is also significant in various ecological and agricultural contexts. It serves as a food source for many insects and animals. Pollen grains are often characterized by their unique shapes and surface textures, which can be used in palynology—the study of pollen and spores. Furthermore, pollen has applications in medicine, nutrition, and environmental science, highlighting its importance beyond its role in plant life cycles.
