Which term refers to the layer that produces cork in a plant?

The term that refers to the layer that produces cork in a plant is indeed the cork cambium. This layer is a type of lateral meristem located just beneath the outer bark of the plant. Its primary function is to generate cork cells, which are part of the protective outer layer of the plant. As cork cells are produced, they become suberized, forming a barrier that protects the plant from physical damage, pathogens, and water loss.

Cork cambium is integral to the process of secondary growth, which allows for an increase in stem girth and enhances the overall structure and durability of the plant. This process is particularly important in woody plants, where the cork cambium continuously generates new cork cells as the plant grows.
