Flower anatomy. Coloured freeze-fracture scanning electron micrograph (SEM) of a flower with the top removed, showing a central ovary (pale pink, centre) containing ovules (green). The ovary contains the ovule, which consists of the female sex cells. Here, it is surrounded by the filaments of the stamen (pink), at the top of which are the anthers (not seen), the male reproductive parts that produce pollen (male sex cells). The purple leaf-like structures are petals. Magnification: x20 when printed 10 centimetres wide.
