Caption: Dragon tree stem. Light micrograph of a section through a dragon tree stem (Dracaena draco). Vascular bundles (round dark structures) can be seen containing xylem (larger openings) and phloem (smaller openings) tissues. Xylem transports water and mineral nutrients from the roots throughout the plant, while phloem transports carbohydrates and plant hormones around the plant. Surrounding these are the cortex (green) and thick-walled woody fibres (red and brown) Magnification: x14 when printed 10 centimetres wide.
