Rosemary leaf. Coloured scanning electron micrograph (SEM) of a freeze-fracture through a leaf from a rosemary plant (Rosmarinus officinalis). The fracture has revealed vascular tissue (red). This tissue is used to transport water and nutrients around the plant. The surface of the leaf (green) is covered in structures called trichomes. These protect the plant from predators and water loss. Magnification: x85 when printed at 10 centimetres wide.
