stratum germinativum first layer of the epidermis above the papillary layer of the dermis also known as the basal layer
stratum germinativum
The Stratum Basale
We find it in the deepest layer of the epidermis called Stratum Basal in which the stem cells undergo Mitosis replacing keratinocytes lost at the stratum corneum, the apical surface of epidermis.
the stratum basale aka germinitivium is the stratum that has miotic division of cells and there is some cell production in the stratum spinosum as well
1st is epidermis, 2nd is subcutaneous and last, the dermis, which is the deepest layer
Nuclear division by mitosis or meiosis

The epidermis is divided into different layers: - Stratum corneum - Stratum lucidum - Stratum granulosum - Stratum spinosum - Stratum basale The stratum basale is made up of the cells which through mitosis replicate several times. Each of these cells goes up towards the surface by being "pushed" by the new cells in formation. Stratum basale is the place of "birth" of the cells that compose the rest of layers which form the epidermis.
Replication does not take place during mitosis. It takes place before meiosis begins.
stratum basale: youngest karatincytes made by stem cells.
melanocytes produces melanin (pigment you're talking about). They are located in the most bottom layer of the epidermis (stratum basale).
