Dead cells on the epidermis help form a protective barrier that shields underlying tissues from damage and infection. They also aid in reducing water loss through the skin and contribute to the skin's ability to sense and respond to external stimuli.
Dead layers on the outside of cells are called the stratum corneum, which is the outermost layer of the epidermis in the skin. These dead cells are composed mainly of keratin and help protect the underlying skin layers.
Most of the skin is composed of the dermis which is made up mostly of dense irregular connect tissue. The cells about it are dead cells called the epidermis.

Root hairs are extensions of root epidermis cells that help increase the surface area of the root for improved absorption of water and nutrients from the soil.
The new skin cells will move up to the surface and replace the dead skin cells.
Your epidermis is your skin, which protects your vital organs, mussels, tissue, blood, and much more.
The characteristics of the epidermis help it in playing its role. It has a thick protective layer and it also has tight junctions within the epithelial cells.
The epidermis consists of several layers of cells, including keratinocytes, melanocytes, Langerhans cells, and Merkel cells. Keratinocytes are the most abundant cells in the epidermis and are responsible for producing the protein keratin, which provides structural support and waterproofing to the skin. Melanocytes produce the pigment melanin, which helps protect the skin from UV radiation. Langerhans cells are part of the immune system and help protect against foreign substances, while Merkel cells are involved in the sensation of touch.
The outermost layer of the skin, called the stratum corneum, is made up mostly of dead cells filled with keratin. These cells provide a protective barrier against environmental stressors and help prevent water loss from the skin.

Plant epidermal cells are found on the outermost layer of plant tissue, covering the surfaces of leaves, stems, flowers, and roots. They serve various functions such as protection, gas exchange, and absorption of water and nutrients.
