Leaf hairs, SEM
Leaf hairs. Coloured scanning electron micrograph (SEM) of the underside of an unidentified leaf, which is covered in numerous hairs (trichomes). These unbranched multicellular hairs may have both a protective function against predators and serve to reduce evaporation from the leaf. Numerous small stomata or pores (orange) serve to exchange gases and water from the leaf surface. Magnification: x40 at 6x7cm size

EDITORS COMMENTS
This print showcases the intricate beauty of leaf hairs, as captured through a coloured scanning electron microscope (SEM). The underside of an unidentified leaf is adorned with numerous trichomes, which are unbranched multicellular hairs. These delicate structures not only serve a protective function against predators but also play a crucial role in reducing evaporation from the leaf's surface. The image reveals the mesmerizing details of these trichomes, highlighting their structural complexity and nature's ingenuity. Each hair appears like a tiny masterpiece, meticulously designed by evolution to safeguard the plant it belongs to. Additionally, small orange stomata or pores can be observed scattered across the leaf's surface. These stomata facilitate the exchange of gases and water between the plant and its surroundings. At a magnification of x40 on a 6x7cm scale, this photograph allows us to appreciate the hidden wonders that lie within even seemingly ordinary leaves. It serves as a reminder that there is so much more to discover about our natural world when we delve into its microscopic realm. This stunning piece from Science Photo Library encapsulates both artistry and scientific exploration, providing us with an awe-inspiring glimpse into the intricate structure of plants' most basic components – their leaves and their remarkable defense mechanisms against threats in their environment.
