Yellow chamomile pollen grain. Coloured scanning electron micrograph (SEM) of a pollen grain from a yellow chamomile (Cota tinctoria) flower, showing its highly sculpted outer wall (exine), which may assist in dispersal. Pollen grains are the male sex cells of a flowering plant. Their characteristic surface is used by botanists to recognise and classify plants.
