melanin
dead cells
They are cells in the leaf epidermis, located arond the stomata. A pair of guard cells open and close each stoma (pore) for gas exchange and transpiration. They are different in shape from the rest of the epidermis cells, and unlike other epidermis cells they also contain chloroplasts.
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
In the living dermis layer of the skin, by normal cell division like other cells. In the dead epidermis surface layer of the skin, they don't as the cells are already dead (they killed themselves before becoming part of the epidermis).
epidermis.
dead cells
Below the upper epidermis and above the lower epidermis.
The living cells in the epidermis are located beneath the dead cells. Hope this helps!Yes but your skin shreds everyday so you may have layers of dead skin forming on the surface of your skin. We shred quite a lot of skin cells everyday but if you're talking about actual layers of skin in which blood runs through then yes, those cells are indeed alive . :)
Cells in the lower layers of the epidermis divide continually, producing new cells that constantly push through the layers of the epidermis. By the time those cells reach the outer layer of the epidermis, they are dead and ready to slough off.
Yes, it is made up of living and dead cells.
The dermis is the layer of skin that contains only living cells. The epidermis contains both living and dead cells.
Tunica
Partially. The dermis and lower part of the epidermis are alive, but the outer layers of the epidermis consist of dead cells.
Pigment cells (melanocytes) are found in the basal layer of the epidermis.
Epidermis is the top layer of skin and the one you can actually see. The dermis is the layer that lies underneath the epidermis, and it is composed entirely of living cells. The most important function of dermis is respiration. The various glands such as the oil and sweat glands originate in the lower dermis. From here, they rise to the surface of the skin to eliminate waste matter.
Melanocytes are pigment cells that synthesize melanin. These cells inject the melanin pigment in the living keratinocytes cells (skin cells) of the stratum basale layer of the epidermis. Note: The Melanocyte cells also reside in the stratum basale.
