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: -The three structures, phellem (cork), phellogen (cork cambium) and phelloderm constitute the periderm, a protective tissue that replaces epidermis in stems and roots, which increase in diameter when secondary growth occurs.

Detailed explanation-3: -The vascular cambium and cork cambium are secondary meristems that are formed in stems and roots after the tissues of the primary plant body have differentiated. The vascular cambium is responsible for increasing the diameter of stems and roots and for forming woody tissue. The cork cambium produces some of the bark.
