Pollen is a fine powder produced by flowering plants that contains their male reproductive cells and comes in many different shapes and sizes depending on the plant species. It plays a crucial role in plant reproduction by traveling between flowers—often carried by wind, insects, or other means—to fertilize plants and enable them to produce seeds.
