Answer
Secondary growth never occurs in leaves. Secondary growth is a type of growth that increases the girth of stems and roots and is primarily found in woody plants. It involves the formation of additional vascular tissues, such as xylem and phloem, and is responsible for the thickening of stems and roots. This growth is facilitated by the vascular cambium and, in some cases, the cork cambium.
In contrast, leaves typically do not undergo secondary growth; they do not increase in thickness in the same way stems and roots do. Secondary growth is mostly restricted to stems and roots.
