Potato leaf, SEM
Potato leaf. 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

EDITORS COMMENTS
This print showcases the intricate beauty and remarkable defense mechanisms of a potato leaf. Through the lens of a scanning electron microscope, we are granted an up-close view of its textured surface adorned with an abundance of hair-like structures known as trichomes. These long spiky appendages serve as nature's armor, safeguarding the plant against both predators and excessive water loss. The trichomes featured in this image possess spherical tips that harbor secretory glands responsible for producing oils. While these oils may be harmless to us, they prove to be quite bothersome for predatory insects seeking to feast on this botanical delicacy. The irritant properties of these secretions act as a potent deterrent, ensuring the survival and well-being of the potato plant. With a magnification level equivalent to 165 times its actual size when printed at 10 centimeters tall, every minute detail is brought into focus. This mesmerizing photograph not only highlights the fascinating biology behind this humble leaf but also serves as a testament to the wonders found within our natural world. Immerse yourself in this enchanting snapshot from Science Photo Library and embark on a journey through botany, protection mechanisms, and biochemical marvels that lie hidden within even the most unassuming flora such as Solanum tuberosum – commonly known as potatoes.
