Caption: Colour-enhanced Scanning Electron Micrograph (SEM) of a mature marijuana (Cannabis sativa) stem in cross section. The different layers of the stem have been given different colours. The layer that is several cells below the skin is the section of thick-walled fiber cells. This highlights one potential uses of cannabis: an excellent source of fibers for paper, rope, and fabric. The legalization of cannabis in the United States opens research in this very profitable aspect of the plant. Magnification: 100X when printed at 10 cm across.
