Explanation:
Detailed explanation-1: -Secondary growth adds to the diameter of a stem or root; vascular cambium adds xylem (inward) and phloem (outward), and cork cambium replaces epidermis with bark. Watch this time-lapse video of plant growth.
Detailed explanation-2: -It is the result of cell division in the shoot apical meristem. Secondary growth is characterized by an increase in thickness or girth of the plant. It is caused by cell division in the lateral meristem. Herbaceous plants mostly undergo primary growth, with little secondary growth or increase in thickness.
Detailed explanation-3: -The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue.
