The epidermis protects plants from mechanical injury, water loss, microorganisms and harsh environmental conditions. Its tightly packed cells and waxy cuticle reduce water loss, while root hairs and stomata help absorption, gaseous exchange and transpiration in plants.
What protects plants from mechanical injury, water loss, harmful microorganisms and extreme environmental conditions?
Share
Plants are protected by the epidermis, the outermost protective tissue covering all plant parts. Its tightly packed cells and waxy cuticle prevent excessive water loss and protect against mechanical damage, microorganisms and environmental stress. Root hairs increase absorption of water and minerals, while stomata help in gaseous exchange and transpiration, supporting proper functioning and survival of plants.
