The vascular cambium in plants is the actively dividing cells between xylem and phloem tissues in the stems and roots of many plants. The cambium is responsible for the secondary growth of stems and roots results in an increase in their thickness or girth. Vascular cambia are found in dicots and gymnosperms but absent in monocots. Due to the absence of vascular cambium in monocots, they usually lack secondary growth.
The cambium comprised of undifferentiated cells which retained their embryonic properties for continued growth and differentiation. The cambial cells divide to produce secondary xylem towards the pith (inward) and secondary phloem towards the bark (outward).
