When These cells Die, They Become Part Of The Surface Layer Of The Epidermis.
Dead cells on the epidermis, known as corneocytes, play a crucial role in providing a protective barrier for the body. These cells are constantly shed and replaced by new cells underneath, helping to maintain the integrity of the skin. Additionally, the dead cells help to prevent water loss and protect the body from external pathogens and UV radiation.
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.
Your epidermis is your skin, which protects your vital organs, mussels, tissue, blood, and much more.
The new skin cells will move up to the surface and replace the dead skin cells.
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 human epidermis is composed of four cell types which are keratinocytes, melanocytes, Langerhans cells, and the Merkels cells.Constituting 95% of the epidermis is the Keratinocytes,making it the major constituent.

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.
