Coloured SEM of a thorn on a rose stem
Rose thorn. Coloured scanning electron micrograph (SEM) of a thorn on the main stem of a rose plant, Rosa sp.. Thorns are short modified branches that terminate in hard sharp points. The huge variety of roses that have been cultivated differ not only in their flower types but in the size and relative number of thorns they possess. The wild rose has small prickles by which it may cling to, and scramble over, vegetation. Larger thorns however, such as the one seen here, can protect the plant from being eaten by large herbivores.

EDITORS COMMENTS
This print showcases the intricate beauty of a thorn on a rose stem. Through the use of scanning electron microscopy (SEM), this image reveals the stunning details of this short modified branch that terminates in a hard, sharp point. Roses, known for their diverse range of flower types, also exhibit variation in the size and number of thorns they possess. The wild rose, for instance, features small prickles that enable it to cling onto vegetation and scramble over surfaces. In contrast, larger thorns like the one depicted here serve as an effective defense mechanism against large herbivores seeking to consume the plant. The magnification employed in capturing this image allows us to appreciate every minute aspect of this rose thorn's structure. At 6x7cm size, we are provided with a closer look at its fascinating composition. However, when enlarged even further at 6x8 inches, we can truly immerse ourselves in its intricate patterns and textures. Nature enthusiasts and botany lovers alike will find themselves captivated by this photograph from Science Photo Library. It serves as a reminder that even seemingly mundane elements such as thorns can possess extraordinary beauty when examined through the lens of scientific exploration.
