What are the differences and similarities between skin and plant epidermis?

Let's start with a similarity. Regardless of whether the epidermis belongs to a plant or an animal, the epidermis is the outermost layer of cells that covers other cell and tissue types. In both types of organisms, the epidermis is a barrier layer. One simple difference between plant epidermis and the skin's epidermis is that the plant's epidermis is also covered in a waxy coating called the cuticle. The cuticle plays a large part in reducing and preventing water loss. In animals, the epidermis also plays an important water role. It is a waterproof layer that prevents water from moving into the body. If skin didn't do this, we would swell up every time we went swimming or took a bath. Another difference is that plants have two layers of epidermis. They have an upper and a lower epidermal layer.
