Sage leaf oil gland
Sage leaf oil gland. Coloured scanning electron micrograph (SEM) of a freeze-fracture section through a leaf of sage, Salvia officinalis, showing an oil gland. At lower frame are leaf cells. On the leaf surface is a spherical structure, a modified glandular hair (trichome), which secretes oils associated with the odour and essence of sage. The leaves of sage are used for cooking. They also have medicinal properties which reduce fever, cleanse the blood, relieve pain, and are antiseptic. Magnification: x478 at 5x7cm size

Circular Glandular Hair Herb Medicinal Oil Gland Plants Rounded Salvia Officinalis Secretory Trichome Cooking Ingredient
EDITORS COMMENTS
This print showcases the intricate beauty of a sage leaf oil gland. In this coloured scanning electron micrograph (SEM), we are granted a close-up view of a freeze-fracture section through a leaf of Salvia officinalis, commonly known as sage. The image reveals an oil gland nestled on the leaf's surface, surrounded by leaf cells. A spherical structure catches our attention - it is a modified glandular hair called trichome. This specialized hair secretes oils that give sage its distinct aroma and essence. Not only cherished in culinary practices as a cooking ingredient, but sage leaves also possess remarkable medicinal properties. Traditionally used for centuries, these leaves have been known to reduce fever, cleanse the blood, relieve pain, and exhibit antiseptic qualities. It is fascinating to witness nature's ingenuity at work within this tiny circular wonder. With magnification set at x478 and printed at 5x7cm size, this photograph allows us to appreciate the delicate details that often go unnoticed by the naked eye. Science Photo Library has once again captured nature's marvels with precision and artistry in this botanical masterpiece.
