Cork and bark are two outer components of woody plants. Bark is composed of cork, cork cambium, phelloderm, cortex, and the secondary phloem. Therefore, cork is a component of the bark. The main difference between cork and bark is their structure and function. Cork serves as a protective barrier whereas bark has other functions such as storage and transport.
