Biology CorkCork cell

Cork cambium is a tissue found in many vascular plants as part of the periderm. The cork cambium is a lateral meristem and is responsible for secondary growth that replaces the epidermis in roots and stems.

cork cambium Meristematic tissue that produces cork cells on its outer surface and phelloderm on its inner surface.
corm Underground, enlarged, food-storing stem covered by papery leaves.
cornea The outer transparent coat of the eye.

Cork cambium. In older stems a meristem forms between the cork and cortex. Mitosis of its cells produces more cork.
Expanded pith rays. Regions of parenchyma that store food. They alternate with
Phloem.

Secondary growth is produced by a cambium. It occurs in rows or ranks of cork, secondary xylem or secondary phloem cells. Cork cells (produced by a cork cambium) are technically part of the epidermis, and contribute to the bark of woody stems.
