Epidermis is the term used to describe the outermost layer of the skin. The epidermis is made up of five layers: stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, and stratum basale. The basal layer repeatedly divides and replaces cells.
The stratum basale, also known as the stratum germinativum, is the deepest layer of the epidermis and the one that gives rise, aka undergoes cellular division, to all the more superficial layers.
"Basal cell layer" divides continuosly to provide proliferation, which continues with differentiation in upper layers to evolve Keratinocytes.
The Stratum Basal is the deepest layer of the epidermis and has some stem cell capabilites of cell division.
Stratum germinativum is the innermost layer and undergoes mitosis
The Stratum Basale Layer is constantly going through mitosis, so it is activaly dividing.
In the stratum basale (deepest layer of epidermis) "Is where a single row of cuboidal or columnar cells that divide and grow." read from a book
Stratum basale
Cell division occurs in the stratum basale of the epidermis. The epidermis is made up of 5 layers. From outer to inner these layers are: stratum corneum, stratum licidum, stratum granulosum, stratum spinosum, and stratum basale. The basale is the innermost layer of the epidermis and is where cell division occurs.
In humans, the epidermis is four or five cell layers thick, depending upon the area of skin in question. There is the cornfield layer, the clear layer, granular layer, spinous layer and basal layer.
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.
epidermis & dermis
The epidermis forms from key specialised stem cells found deeper under the outer layer. These stem cells are found in or on top of the dermis and grow into the epidermis. These cells in grow in layers and as the layers age, the cells undergo a process called 'keratinisation' almost completely changing into the protein keratin. The last part of the cell that is converted is the nucleus.

There are actually three layers of skin: the epidermis, the dermis, and the hypodermis.
Melanin is the pigment that helps protect the deepest layers of the epidermis.
The epidermis cell is located on the outer layers of a leaf. It is protected by a wax-like layer.
The epidermis does not but the lower layers of the dermis do.

The main layers are epidermis and Dermis

The cells in skin, or epidermis, regenerate on a daily basis.
