A type of meristem found in the bark of plants that produces cork cells to provide protection and reduce water loss.

Periderm

A protective outer layer of tissue in plants, replacing the epidermis in parts of the stems and roots, consisting of the cork, cork cambium, and phelloderm.

Xylem

The vascular tissue in plants responsible for the conduction of water and nutrients from the roots to the leaves and other parts.

Vascular Cambium

The vascular cambium is a layer of stem cells located between the xylem and the phloem in dicots and gymnosperms, responsible for producing new layers of vascular tissue and contributing to stem growth.
