How Does Cork Act as a Protective Tissue?

Cork protects the plant by forming a waterproof and tough outer layer made of dead cells that prevent water loss, injury, and infection.

Cork is a protective tissue found in plants, especially in older stems and branches. It forms the outer bark and keeps the plant safe from damage and water loss. Cork is made up of dead, tightly packed cells filled with a waxy substance called suberin, which acts like a shield.

Why Cork Is a Good Protective Tissue

• Cork replaces the epidermis in mature plants.
• It is part of the periderm, which is the plant’s second protective skin.
• Suberin makes cork cells non-living but strong and resistant.
• Cork is used in real life too (like wine bottle stoppers) because of its waterproof and insulating nature.

Conclusion

Cork works like a natural shield for plants. Its dead, suberin-rich, and tightly packed cells stop water from escaping, protect against injuries, and block harmful germs and pests. That’s why cork is an important protective tissue that helps plants survive in different environments.
