Sweet potato stem, light micrograph
Sweet potato stem. Light micrograph of a transverse section through part of a sweet potato (Ipomoea batatas) stem. At bottom is a large area of pith, consisting of parenchyma cells. Above this are xylem (red) and then phloem (blue) cells, which transport water and carbohydrates around the plant respectively. Next is a very thin ring of parenchyma cells (dark pink) and then collenchyma tissue (blue and black), before the outer layers of epidermis and cuticle. Magnification: x100 when printed at 10 centimetres wide

EDITORS COMMENTS
This stunning print captures the intricate beauty of a sweet potato stem like never before. The light micrograph reveals a transverse section of the stem, showcasing its complex anatomy and functionality. At the bottom, we see a vast area of pith composed of parenchyma cells, responsible for storing nutrients and providing structural support. Above the pith, we encounter two distinct cell types: xylem (in red) and phloem (in blue). These specialized tissues play crucial roles in transporting water and carbohydrates throughout the plant respectively. A delicate ring of dark pink parenchyma cells surrounds them, followed by collenchyma tissue depicted in shades of blue and black. This outer layer provides additional strength to withstand external pressures. Finally, we reach the outermost layers consisting of epidermis and cuticle which protect the stem from environmental factors. The magnification level used for this print allows us to appreciate these intricate details at an impressive scale. This mesmerizing image not only showcases nature's incredible complexity but also serves as a valuable tool for botanical research and education. It highlights how different cellular components work together harmoniously within plants like sweet potatoes to ensure their growth, survival, and ability to produce delicious tubers that are enjoyed worldwide.
