Caption: Evening primrose pollen. Coloured scanning electron micrograph (SEM) of evening primrose (Oenothera biennis) pollen grains. Pollen grains are the male gametes (sex cells) of a plant. These pollen grains exude a sticky thread known as viscin, which sticks to pollinating insects aiding the spread of the grains.
