Macrophotograph of the roots of a small Lawson's cypress tree,Chamaecyparis lawsoniana,showing the different stages of development of the root tissues. The tip of each root,where cell division is occurring,is white. Just above this is a greyish-white region where cell enlargement occurs. The mature,brown tissue above this has ceased to elongate and the cells are differentiating into different tissue types | |
