Explanation:
Detailed explanation-1: -A cylindrical layer of tissue in the stems and roots of many seed-bearing plants, consisting of cells that divide rapidly to form new layers of tissue. Cambium is a kind of meristem and is most active in woody plants, where it lies between the bark and wood of the stem.
Detailed explanation-2: -The cambium cell layer is the growing part of the trunk. It annually produces new bark and new wood in response to hormones that pass down through the phloem with food from the leaves. These hormones, called “auxins”, stimulate growth in cells.
Detailed explanation-3: -The cambium present between primary xylem and primary phloem is called the intrafascicular cambium (within vascular bundles).
