Stinging nettle leaf. Coloured scanning electron micrograph (SEM) of a freeze-fracture of a leaf from a stinging nettle plant (Urtica dioica). Trichomes (hair-like) are seen on the upper and lower leaf surfaces, while the freeze-fracture has revealed the internal cellular structure. Nettles have stinging trichomes (not seen) and non-stinging trichomes (these shorter ones). Magnification: x67 when printed at 10 centimetres across.
