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 thus they provide strong mechanical strength to plants.
- Cells of cork are dead at maturity.
- These cells are compactly arranged.
- Cells do not posses intercellular spaces.
- Cells possess a chemical substance ‘suberin’ in their walls.
- There are several thick layers.
As plants grow older, 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.
