Légende : Chinese hibiscus pollen. Coloured scanning electron micrograph (SEM) of a pollen grain from a Chinese hibiscus (Hibiscus rosa-sinensis) flower. Pollen grains are the male gametes (sex cells) of a plant. They are microscopic, usually about 15 to 100 microns across, and just a pinch of pollen powder contains thousands and thousands of grains. Magnification: x800 when printed at 10 centimetres wide.
