The importance of epidermis is as follows : 1. It is the outer protective layer which prevents the pathogenic invasions. 2. Water loss is also controlled through the aerial parts. 3. The presence of stomata helps in gaseous exchange and transpiration. 4. The root epidermis go deeper in search of water and minerals. 5. The dense root hair fibres increase the surface area of absorption.
