Explanation:
Detailed explanation-1: -This layer is one of the most important layers of our skin. This is because it contains the only cells of the epidermis that can divide via the process of mitosis, which means that skin cells germinate here, hence the word germinativum.
Detailed explanation-2: -Mitosis takes place in the stratum germinativum, the outermost layer.
Detailed explanation-3: -The cells of the stratum basale are cuboidal and undergo mitosis to give rise to all of the cells in the layers above.
Detailed explanation-4: -The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells. The basal cell layer contains cells called melanocytes.
