The primary function of cork cells is to provide a protective barrier for the underlying tissues, as they are dead and compactly arranged, impervious to gases and water due to the presence of suberin in their walls.

The primary function of cork cells in the outer protective tissue of a plant, known as the cork cambium or phellogen, is to provide a protective barrier against physical damage, pathogens, and water loss. Cork cells are impregnated with suberin, a hydrophobic substance that makes them impermeable to water and gases, enhancing their protective qualities. Additionally, cork cells contribute to the structural integrity and longevity of the plant’s stem and roots.
