In dicotyledonous and coniferous (i.e., woody) trees and shrubs, the defining structure that permits this conversion is a layer of meristematic cells, called the vascular cambium, that organizes between the primary xylem and primary phloem of the vascular cylinders. Tree stumps are generally regarded as nuisance tripping hazards, the unwanted remains of an unwanted tree. Trunk wounds that penetrate the bark will damage the cambium layer, a thin layer of vascular tissue, which is vital to movement of water and nutrients. Exclusively classical!
