Rosemary (Rosmarinus officinalis), coloured scanning electron micrograph (SEM). Cross-section through the stem of a rosemary plant, showing xylem vascular tissue for transporting water and mineral nutrients from the roots to the main body of the plant. The hairs protect the plant from being invaded by other organisms. This perennial herb is used in herbal medicine to treat headaches and colds. It is also used as a tonic and as a food flavouring. Magnification: x32 when printed 10 centimetres high.
