Meristematic tissues can be categorised based on their functions. These tissues are mostly present at the tips of roots and stems. These are protoderm, procambium and ground meristem. Protoderm gives rise to the epidermal tissue system in the body of a plant. This meristematic tissue is present in the outermost layer of the plant. It protects plants from mechanical shock. It also helps in the formation of the epidermis in the body of a plant.
