Hi There,

Epidermis and cork cells are both types of plant cells, but they serve different functions and are found in different parts of the plant.

The epidermis is a general outer layer of plant organs that serves various functions like protection and water regulation. They contain specialized cells, such as guard cells (in leaves) and root hair cells (in roots), which have specific functions in gas exchange and absorption.

Cork cells form part of the outer bark which provide structural support and protection in woody plants. The cells are filled with a substance called suberin, which makes them impermeable to gases and water.
