The cambium is a layer of cells in plants that produces new tissues such as xylem and phloem. The cambium is located between the xylem and the phloem, and it is responsible for the secondary growth of woody plants. The cambium cells divide and differentiate into either xylem cells, which transport water and minerals, or phloem cells, which transport sugars and organic molecules. The cambium also forms cork cells, which protect the plant from external damage and water loss.
