Editing Cork (material) (section)

==Structure==
Cork presents a characteristic [[wikt:cellular|cellular]] structure in which the [[Cell (biology)|cells]] have usually a pentagonal or hexagonal shape. The cellular wall consists of a thin, lignin-rich middle [[Lamella (cell biology)|lamella]] (internal primary wall), a thick secondary wall made up from alternating suberin and wax lamella, and a thin tertiary wall of polysaccharides. Some studies suggest that the secondary wall is lignified, and therefore, may not consist exclusively of suberin and waxes. The cells of cork are filled with a [[gas]] [[mixture]] similar to air, making them behave as authentic "pads," which contributes to the capability of cork to recover after compression.<ref name="Duarte 2015"/>
