What is the cambium layer of a tree responsible for?

The cambium layer of a tree plays a crucial role in the growth and regeneration of the tree. This thin layer of active cell division is located between the bark and the wood, specifically responsible for producing new layers of cells. As the cambium divides, it generates new xylem (wood) cells on the inside, which helps increase the tree's width, and new phloem (bark) cells on the outside, which aids in transporting nutrients from the leaves to various parts of the tree.

This process of continual growth allows trees to increase in size and support their expanding structure over time. The cambium is vital for maintaining the overall health of the tree, ensuring that it can regenerate when pruned or damaged, and contributes significantly to the tree's longevity and vitality.
