<P> The cells of the epidermis are structurally and functionally variable . Most plants have an epidermis that is a single cell layer thick . Some plants like Ficus elastica and Peperomia , which have periclinal cellular division within the protoderm of the leaves , have an epidermis with multiple cell layers . Epidermal cells are tightly linked to each other and provide mechanical strength and protection to the plant . The walls of the epidermal cells of the above ground parts of plants contain cutin , and are covered with a cuticle . The cuticle reduces water loss to the atmosphere , it is sometimes covered with wax in smooth sheets , granules , plates , tubes or filaments . The wax layers give some plants a whitish or bluish surface color . Surface wax acts as a moisture barrier and protects the plant from intense sunlight and wind . The underside of many leaves have a thinner cuticle than the top side , and leaves of plants from dry climates often have thickened cuticles to conserve water by reducing transpiration . </P>
