The basal cells continually divide, and new cells constantly push older ones up toward the surface of the skin, where they are eventually shed. The basal cell layer is also known as the stratum germinativum due to the fact that it is constantly germinating (producing) new cells.
The stratum germinatum (SG) provides the germinal cells necessary for the regeneration of the layers of the epidermis. These germinal cells are separated from the dermis by a thin layer of basement membrane.
Option H - True: The epidermis is the skin's "outermost layer" that mainly consists of "keratinocytes" that produces a protein called as "keratin". Approximately 90% of the epidermis is made of the said cells. "Thank you !"
The epidermis is the thinnest layer of skin, but it's responsible for protecting you from the outside world, and it's composed of five layers of its own.
What does the stratum germinativum (basal cell layer) do? It is the deepest layer of the epidermis and is the live layer that produces new cells. It also contains melanocytes.
Stratum germinativum (also stratum basale or basal cell layer) is the layer of keratinocytes that lies at the base of the epidermis immediately above the dermis. It consists of a single layer of tall, simple columnar epithelial cells lying on a basement membrane.
While it is true that the entire epidermis functions as an anti-pathogen barrier, it is not true that the entire epidermis is made up of dead cells. The stratum germinativum is made up of living, cells capable of mitosis and producing new cells.
The epidermis is made up of stratified squamous epithelial cells called keratinocytes. It functions primarily as a protective barrier and also provides touch sensation.
Stratum Basale. The innermost layer of the epidermis whose cells are involved in cell division.
Dermal white adipose tissue is a unique layer of adipocytes within the reticular dermis of the skin.
stratum lucidumThick skin is thicker due to it containing an extra layer in the epidermis, called the stratum lucidum. Thick skin actually has a thinner dermis layer than thin skin, but is still thicker due to the stratum lucidum layer present in the epidermis.
The cells of the stratum granulosum (SGR) accumlate dense basophilic keratohyalin granules (seen on the close-up view). These granules contain lipids, which along with the desmosomal connections, help to form a waterproof barrier that functions to prevent fluid loss from the body.
Stratum basale, also known as stratum germinativum, is the deepest layer, separated from the dermis by the basement membrane (basal lamina) and attached to the basement membrane by hemidesmosomes.

EXPLANATION: Stratum germinativum is also known as basal cell layer or stratum basale. It is the layer of keratinocytes, which lies at the base of the epidermis. It is made up of single layer of tall, simple columnar epithelial cells.
The stratum basale, also called the stratum germinativum, is the basal (base) layer of the epidermis. It is the layer that's closest to the blood supply lying underneath the epidermis. This layer is one of the most important layers of our skin.
