A Correct answer
Explanation

As a plant grows older, the outer protective layer is replaced by cork cells. These cells produce and deposit suberin in their walls, which is a waxy, fatty substance that is highly impermeable to water and gases. This makes the cork an excellent protective and insulating layer.
