epidermis

  2. The outer layer of cells of the stems, roots, and leaves of plants. In most plants, the epidermis is a single layer of cells set close together to protect the plant from water loss, invasion by fungi, and physical damage. The epidermis that is exposed to air is covered with a protective substance called cuticle. See more at photosynthesis.
