Ladybell flower pistil. Coloured scanning electron micrograph (SEM) of a ladybell flower (Adenophora triphylla) pistil. Pollen grains (round,green) are seen on the pistil. Pistils hold a plant's female reproductive structures. They contain one or more carpels,which,in turn,contain a stigma,style and an ovary. Within the ovaries are the ovules,the female gametes (sex cells). The ovaries are fertilised by pollen grains,the male gametes. Magnification: x570 when printed at 10 centimetres wide | |
