Cork tissue, with its impervious nature and protective function, is a distinctive feature of complex plants that has enabled their survival in terrestrial environments. It provides an effective barrier against water loss and protects against mechanical injury and microbial infections.

Cork tissue is crucial for the survival of complex plants in terrestrial environments due to its protective and structural functions. The suberized cell walls of cork cells create a waterproof and resistant barrier, reducing water loss and protecting against pathogens, insects, and mechanical damage. This insulation is vital for plants exposed to diverse environmental stresses in terrestrial habitats. Additionally, cork provides structural support as part of the plant’s outer bark, aiding in stem and branch integrity. The continuous production of cork cells by the cork cambium ensures long-term protection, contributing significantly to the adaptability and resilience of complex plants in terrestrial ecosystems.
