Convolvulus pollen grains, SEM
Convolvulus pollen grains. Coloured scanning electron micrograph (SEM) of pollen grains from a convolvulus flower.Convolvulus is a genus of about 200 to 250 species of flowering plants in the bindweed family Convolvulaceae, with a cosmopolitan distribution. Pollen grains are the male sex cells of a flowering plant. Their characteristic surface is used by botanists to recognise and classify plants. Pollen in plants is used for transferring male genetic material from the anther of a single flower to the stigma of another in cross-pollination. In a case of self-pollination, this process takes place from the anther of a flower to the stigma of the same flower Magnification: x500 when printed at 10 centimetres wide
