Sweet potato leaf. Light micrograph of a transverse section through the midrib of a sweet potato (Ipomoea batatas) leaf. The semicircular structure at centre is the vascular bundle. It consists of phloem (blue and green) and xylem (red) cells, which transport carbohydrates and water around the plant respectively. Across the top of the leaf are palisade cells (bright green), which contain chloroplasts, the site of photosynthesis. Magnification: x45 when printed at 10 centimetres wide.
