Which of the following is true of the stratum germinativum?

The stratum germinativum, also known as the stratum basale, is the deepest layer of the epidermis. This layer is primarily responsible for the generation of new skin cells through the process of cell division. It sits directly above the dermis, where it can access a rich supply of blood vessels that deliver essential nutrients and oxygen to the cells. This close proximity to the dermis is crucial for the health and regeneration of the skin, as these nutrients support the metabolic activities needed for cell growth and turnover.

In contrast, the outermost layer of the skin is the stratum corneum, which is composed of dead skin cells, indicating that the first choice is not applicable. The stratum germinativum is actively involved in the development of new skin cells, rather than being primarily made up of dead cells, which aligns with the second choice being incorrect. While the epidermis does play a role in providing some protection against UV radiation, this function is more associated with the outer layers of the skin that contain keratin and melanin rather than the stratum germinativum itself, so the final statement about UV protection does not accurately represent the primary function of this layer.

Thus, the correct answer highlights that the
