Anemone pollen grains. Coloured scanning electron micrograph (SEM). Anemone is a genus of about 120 species of flowering plants in the family Ranunculaceae,native to the temperate zones. 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 x 1500 at 10cm wide | |
