cambial zone

This term is a specialized botanical expression used primarily in plant anatomy and physiology. It describes the specific region of the vascular cambium, the lateral meristem responsible for secondary growth. The term is highly technical and is almost exclusively found in academic textbooks, scientific papers, or professional horticultural discussions.

Because it refers to a specific biological structure, it is typically used in a descriptive, objective manner. It is often paired with terms like secondary growth, xylem, and phloem to explain the mechanism by which woody plants increase their diameter over time.
