Elaeagnus leaf
Elaeagnus leaf. Coloured scanning electron micrograph (SEM) of leaf hairs on the surface of a leaf of an Elaeagnus pungens plant. Outgrowths from the surface of a plant are called trichomes. The hairs reduce evaporative water loss from the stomata below them. Stomata are plant pores through which gases are exchanged between the air and the plant. E. pungens is a drought-resistant shrub.

Evaporation Prevention Hairs Plants Trichomes Water Loss
EDITORS COMMENTS
This print showcases the intricate beauty of an Elaeagnus leaf. The coloured scanning electron micrograph (SEM) reveals the delicate leaf hairs that cover its surface, known as trichomes. These outgrowths serve a vital purpose in reducing evaporative water loss from the stomata beneath them. Stomata are tiny pores through which gases are exchanged between the plant and its surroundings. The image highlights nature's ingenious design to combat dehydration, as these fine hairs act as a protective shield against excessive evaporation. Each hair is meticulously captured, revealing their role in preventing water loss and maintaining optimal hydration levels within the leaf. Elaeagnus pungens, the featured shrub species, possesses this remarkable adaptation to thrive in arid conditions. Its drought-resistant nature makes it resilient even during prolonged dry spells when other plants struggle to survive. At a magnification of x78 and printed at 6x7cm size, this photograph allows us to appreciate the intricacies of plant biology on a microscopic level. It serves as a reminder of how every element in nature has evolved with unique features tailored for survival. Science Photo Library brings us yet another stunning visual representation of botanical wonders that not only fascinate but also deepen our understanding of the natural world around us.
