Dermal tissue is a thin layer of cells covering the soft parts of a plant.
The dermal tissue system protects the soft tissues of plants and controls interactions with the plants' surroundings.
The epidermis is a dermal tissue that is usually a single layer of cells covering the younger parts of a plant.
It secretes a waxy layer called the cuticle that inhibits water loss.
The dermal tissue system—the epidermis—is the outer protective layer of the primary plant body (the roots, stems, leaves, flowers, fruits, and seeds).
