What is Cork cell?
A mature cork cell is non-living and has cell walls that are composed of a waxy substance that is highly impermeable to gases and water called suberin. The layer of dead cells formed by the cork cambium provides the internal cells of the plants with extra insulation and protection. ...
What is the function of cork?
The walls of cork cells contain a chemical called suberin, which makes them impermeable to water and gases. Thus, cork cells prevent water loss from plants and also make them more resistant to bacterial and fungal infection.
