Which structure is produced by the cork cambium in plants?

The structure produced by the cork cambium in plants is bark. The cork cambium is a type of lateral meristem, which primarily contributes to the secondary growth of the plant. It gives rise to cork cells, which make up the outer protective layer of stems and roots. This layer of cork is known as bark when it includes both the cork and the phloem, which is the inner layer that transports nutrients.

The cork cells are impregnated with suberin, a waxy substance that helps protect the plant from physical damage and prevents water loss. As the plant grows, more cork cambium produces additional layers of cork, contributing to the thickening of the bark over time. This functional role of the cork cambium in producing bark is crucial for the plant's ability to survive in various environments and is an essential component of many woody plants.
