Potato leaf (Solanum tuberosum)
Ref: 80019726Description:
Coloured scanning electron micrograph (SEM) of the surface of a potato leaf (Solanum tuberosum). It is covered in hair-like growths called trichomes. The long spiky trichomes protect the plant against predators and water loss through evaporation. The trichomes with spheres at their tips secrete oils that are irritating to predatory insects. Magnification: x165 when printed at 10 centimetres tall.
