Flower stigma. Coloured scanning electron micrograph (SEM) of a flower's stigma (orange) and style (brown). These are part of a plant's female reproductive structures. Pollen grains,a flower's male reproductive cells,land on the stigma and burrow a tube down through the style to the ovary,where they fertilise the female sex cell (ovule).
