3rd detail: The vascular cambium is found in divots; which are flowering plants. But not in monocots. some type of leave also have vascular cambium.
4th detail: The phytohormones are involved in vascular activity; auxins, ethylene, gibberellins, cytokininis etc..
5th detail: The vascular cambium is maintaned by a network of interacting signal feedback loops, so the plant or tree could keep it's protection.
