Secondary meristem, located in the cortex of the plant, contributes to the formation of cork cells by generating layers of cells that constitute the cork, thus aiding in the development of the protective outer layer as the plant grows older.

Secondary meristem, specifically the cork cambium or phellogen, produces cork cells in a process called secondary growth. Cork cells, formed by the division and differentiation of cork cambium cells, constitute the outer bark of woody plants. These cells provide protection and structural support, forming a waterproof barrier that helps prevent water loss, mechanical damage, and pathogen invasion, contributing to the overall integrity of the plant’s stem and roots.
