Detailed explanation-1: -Cork cambium (pl. cambia or cambiums) is a tissue found in many vascular plants as a part of the epidermis. It is one of the many layers of bark, between the cork and primary phloem. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

Detailed explanation-2: -It comprises the phelloderm, cork, and cork cambium cells. The phellem or the cork forms the exterior of the cork cambium. When mature, they comprise dead cells. The phelloderm is a thin layer of parenchyma cells (living) that forms within each of the several cork cambia.

Detailed explanation-3: -cambium, called the phellogen or cork cambium, is the source of the periderm, a protective tissue that replaces the epidermis when the secondary growth displaces, and ultimately destroys, the epidermis of the primary plant body.

Detailed explanation-4: -In woody plants, the tough, waterproof outer layer is known as bark which is made of cork cells derived from cork cambium. The cork in the stem protects the plant from damage like parasites, herbivory, and diseases.
