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).
