Gorse (Ulex europaeus) flower bud, coloured scanning electron micrograph (SEM). One of the petals (yellow) is seen enclosed in the flower casing (calyx). The calyx consists of sepals (green), leaf-like structures that protect the flower bud. Trichomes are seen on the sepal surfaces, giving them a hairy appearance compared to the smooth surface of the petal. Magnification: x20 when printed at 10 centimetres across.
