Cambium

This photo is a tree trunk. The tree trunk reveals the cambium of the tree. The cambium is the plant membrane located right behind the bark of a woody tree or plant. In woody plants, such as the tree in the photo, the cambium produces layers of xylem and phloem. It also creates secondary growth of roots and stems. In other plants, the cambium acts as a healing agent. In an injured plant, the cambium may form in callus cells and encourage the growth of new cells. Callus cells are cells that cover wounds in plants. The roots and stems of woody trees or plants consist of three main types of cambium: vascular cambium, uni-facial cambium, and cork cambium. Vascular cambium is the primary cambium that contains special cells called meristem that produce fresh vascular tissues. Uni-facial cambium grows and appears in the middle of the plant; this tissue later becomes a xylem. A xylem is a vascular tissue that carries water and nutrients upward from the roots. Cork cambium is tissue where the plant grows; it helps repair and replace the epidermis of the roots.
