Heather leaf, light micrograph
Heather leaf. Light micrograph of a transverse section through the leaf of a heather (Erica sp.) plant. Heather is a drought plant (xerophyte). Xerophytes have evolved an anatomy that cuts down water loss through transpiration. The epidermis consists of thick-walled cells covered in a thick cuticle (light-pink). Underneath this are the cells of the palisade mesophyll and spongy mesophyll containing chloroplasts where photosynthesis takes place. Magnification: x234 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate beauty of a heather leaf, as seen under a light microscope. The transverse section through the leaf reveals the fascinating adaptations of this xerophytic plant, which has evolved to thrive in dry environments. The image highlights the remarkable anatomy that enables heather plants to minimize water loss through transpiration. The thick-walled cells of the epidermis are coated with a protective cuticle, depicted here in a delicate shade of light pink. These features act as barriers against excessive evaporation. Beneath the epidermis lie two distinct layers: the palisade mesophyll and spongy mesophyll. Both contain chloroplasts responsible for photosynthesis, where sunlight is converted into energy for growth and survival. With a magnification factor of 234 when printed at 10 centimeters wide, this micrograph allows us to appreciate nature's ingenuity on an intimate level. It reminds us that even seemingly ordinary leaves possess extraordinary adaptations shaped by millions of years of evolution. This mesmerizing image from Science Photo Library captures not only the scientific marvels within plants but also serves as a testament to their resilience and ability to adapt to challenging arid conditions. Whether you're fascinated by biology or simply admire botanical wonders, this photograph invites you into an awe-inspiring world where form meets function in perfect harmony.
