Detailed explanation-1: -Cork cambium is a thin layer of undifferentiated meristematic cells in the outer covering, or periderm, of the stems and trunks of woody plants. This covering contains cork cells and, along with the layer of cells beneath it called secondary phloem, is commonly referred to as the bark of a plant.

Detailed explanation-2: -Cell division by the cambium produces cells that become secondary xylem and phloem. As secondary phloem and xylem tissue accumulates, it both increases the girth of the stem and forms wood and bark.

Detailed explanation-3: -As growth proceeds, the cork cambium forms in living cells of the epidermis, cortex, or, in some plants, phloem and produces a secondary protective tissue, the periderm.

Detailed explanation-4: -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-5: -phellogen (cork cambium) – meristem that gives rise to periderm.
