Cork cambium is a type of lateral meristem found in the stems and roots of woody plants. It is responsible for producing cork cells, which form the outer protective layer of the plant, known as the periderm. This layer helps to prevent water loss and protects the plant from environmental damage. As the plant grows, the cork cambium continuously divides, creating new cork cells that replace older ones. This process contributes to the thickening of the bark over time. The cork cambium plays a crucial role in the overall health and survival of trees and other woody plants.
