Cornflower pollen. Coloured scanning electron micrograph (SEM) of pollen grains (brown) of the cornflower (Centaurea cyanus). Pollen are the male sex cells of a flowering plant. The cornflower is pollinated by insects,usually bees. When an insect lands on the flower the stamens (green) release the grains as a response to being disturbed. The pollen grains are then carried to another flower by the insect,where they fertilise the female parts of the flower | |
