Caption: Flower stigmas. Coloured scanning electron micrograph (SEM) of the stigmas (feathery parts) and styles (stalks) of a marsh mallow flower (Althaea officinalis). These are part of the flower's female reproductive parts. Pollen grains, a flower's male reproductive cells, land on a stigma and burrow a tube down to the ovary, where they fertilise the female sex cell (ovule). Magnification: x80 when printed at 10 centimetres tall.
