Pansy flower reproductive parts. Coloured scanning electron micrograph (SEM) of reproductive parts from the flower of a pansy (Viola sp.) plant. Male reproductive parts (anthers) are coiled at centre, while petals surround them. Anthers are sacs that contain the pollen grains that are male gametes (reproductive cells). Many papillae (projections) are seen on the flower surfaces. Magnification: x14 at 6x7cm size.
