What is the cambium layer primarily responsible for in a tree?

The cambium layer is primarily responsible for producing new growth layers in a tree. This tissue is a thin layer of actively dividing cells located between the bark and the wood of the tree. The cambium generates new cells that differentiate into either phloem (which transports food produced during photosynthesis) or xylem (which transports water and nutrients from the roots). As new layers of xylem and phloem are added, they contribute to the tree's growth in diameter, which is essential for the structural stability and overall health of the tree. This growth process is vital for the tree to increase its height and girth over time, accommodating its expanding structure and needs.
