Cambium

Cambium

The tip of the wood in the photo above is the cambium. The cambium is the first layer found past the bark and living phloem. It is a layer of actively dividing cells with the responsibility of secondary growth of stems and roots. The cambium is technically a single layer of cells known as the initial cells. The cambium originates from undifferentiated cells that have retained their embryonic capacity for continued growth and development.
