The thin walls of those cells are saturated with a fatty waxy substance, called suberin, which makes cork almost impervious to water and air. Suberin is the chemical present in cell wall of cork that makes it impervious to gases and water. Lignin is a complex polymer which acts as a cement and hardens the cell wall. The walls of cork cells are heavily thickened with an organic substance, suberin. Suberin makes these cells impervious to water and gases.
