Caption: Oak tree pollen. Coloured scanning electron micrograph (SEM) of pollen grains (green) from an oak tree (Quercus robur). Pollen grains contain the male sex cells of a flowering plant. Millions of pollen grains are produced by each flowering plant. In the process of pollination, some of these pollen grains are transported from a flower's anthers to the female reproductive parts of a plant. This allows the female and male sex cells to combine in the formation of a seed, in this case, an acorn. Magnification: x410 at 10 centimetres wide.
