DENDROLOGY

Detailed explanation-1: -Vascular cambium is a thin layer of cells found in plants, separating two other types of plant vascular tissue, xylem and phloem. These cells divide and multiply with the plant’s secondary growth, in which it increases in girth size.

Detailed explanation-2: -Xylem and phloem tissues are produced by meristematic cambium cells located in a layer just inside the bark of trees and shrubs. In dicot stems, the cambium layer gives rise to phloem cells on the outside and xylem cells on the inside.

Detailed explanation-3: -cambium, plural Cambiums, orCambia, in plants, layer of actively dividing cells between xylem (wood) and phloem (bast) tissues that is responsible for the secondary growth of stems and roots (secondary growth occurs after the first season and results in increase in thickness).

Detailed explanation-4: -C: 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.
