Flower anthers (white). Coloured scanning electron micrograph (SEM) of two anthers. These are the male reproductive parts of a plant, found at the centre of the flowers. Each anther is supported by a filament (green). Together, the filament and the anther make up the stamen. The anthers release pollen (male sex cells). The petals of the flower (yellow) are seen in the background. This flower is from a chameleon plant (Houttuynia cordata).
