How does the cork act as a protective tissue?
Cork acts as a protective tissue because its cells are dead and compactly arranged without intercellular spaces. They have deposition of suberin on the walls that make them impervious to gases and water.
Cork is the part of the periderm that protects inner plant tissues from mechanical injury, water loss, and infections; made of dead, mature cells packed with air, tannins, or resins.
The epidermis is replaced by bark in woody plants. Periderm, cortex, and phloem make up the bark. The periderm consists of cork, cork cambium, and phelloderm. The cork cambium produces new cells by mitosis. New cells make the phelloderm and cork (outer layer). Woody plant roots and stems have cork cells instead of the epidermis. At maturity, these cells die and fill with air or resins or tannins. Cork is harder than the epidermis and protects against water loss, infections, and mechanical trauma.
Oak cork is commercially extracted. It's used to make bottle stoppers, fishing floats, and fishing rod handles.
