Stinging nettle leaf, light micrograph
Stinging nettle leaf. Polarised light micrograph of the underside of a stinging nettle (Urtica dioica) leaf. Two types of hairs are seen, the hairs with a bulbous base are the stinging hairs and the smaller curved ones are non-stinging hairs. This image was created using an epithelial peel to chemically remove the top layer of the leaf. Magnification: x44 when printed at 10 centimetres tall

EDITORS COMMENTS
This print showcases the intricate beauty and remarkable defense mechanisms of a stinging nettle leaf. Under the polarized light micrograph, we are granted a glimpse into the hidden world of this botanical wonder. The underside of the leaf reveals two distinct types of hairs: those with bulbous bases, known as stinging hairs, and smaller curved ones called non-stinging hairs. The image was meticulously created using an epithelial peel technique that chemically removed the top layer of the leaf, allowing us to appreciate its anatomical details at a magnification of x44 when printed at 10 centimeters tall. It is through such scientific artistry that we can truly grasp nature's ingenious designs. Stinging nettles have long been renowned for their protective properties in botany. These tiny needles act as formidable defenders against potential threats, deterring animals and humans alike from disturbing their delicate foliage. This photograph serves as a testament to both their defensive capabilities and their role within plant biology. As we marvel at this stunning visual representation, let us not forget to acknowledge Science Photo Library for capturing this moment in time—a reminder that even seemingly ordinary flora possess extraordinary qualities worth exploring and appreciating.
