Fine powdery grains produced by anthers, containing the male gametes necessary for plant reproduction. Each grain has a tough outer wall and carries sperm cells to fertilize ovules.
From Latin 'pollen' meaning 'fine flour' or 'dust,' referring to the powder-like appearance of these reproductive particles. The term was first used scientifically in the 17th century when microscopes revealed their cellular nature.
Pollen grains are like microscopic spaceships with incredibly tough shells - some can survive thousands of years and travel hundreds of miles, and each species has its own unique sculptural design visible only under a microscope!
