In contrast to animal cells, most plant cells cannot undergo cell division. Instead, cell division, and thus growth of the organism, is restricted to a few specialized areas called meristems . Examine the slides of angiosperm and gymnosperm woody branches. Make sure that you can identify the location of the vascular cambium, xylem and phloem in each. These slides show a few tree rings, each ring corresponding to one year of growth.
Complete answers explain the role of the vascular cambium.
