As plants grow older, the outer protective tissue undergoes certain changes. A strip of secondary meristem replaces the epidermis of the stem. Cells on the outside are cut off from this layer. This forms the several-layer thick cork or the bark of the tree. Cells of cork are dead and compactly arranged without intercellular spaces. They also have a chemical called suberin in their walls that makes them impervious to gases and water.
As we know (from my previously answered question), Cork plays an important role in the industrialised sections of the Indian market. They void of the animals from eating the inner soft layers by producing a hard covering (given by the cork).
