AI overview

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.

Pollen is a powdery substance produced by most types of flowers of seed plants for the purpose of sexual reproduction. It consists of pollen grains (highly reduced microgametophytes), which produce male gametes (sperm cells).
