Coloured-enhanced Scanning Electron Micrograph (SEM) of a section through a xylem vessel in a marijuana (Cannabis sativa) stem. The xylem transports water and mineral nutrients from the roots to the rest of the plant. The walls of the xylem vessels are strengthened with lignin,a woody substance that helps to support the plant. Magnification: 2200X when printed at 10 centimetres wide | |
