What are somatic cells?

Somatic cells are defined as any cells in the body that are not involved in reproduction. This includes a wide variety of cell types that make up tissues and organs, such as skin, muscle, nerve, and blood cells, among others. They are distinct from germ cells, which are involved in the reproductive process and give rise to gametes (sperm and eggs).

Since somatic cells encompass all other bodily cells, choosing the option that specifies "any cells that are not reproductive cells" accurately captures the definition. This highlights the essential distinction between somatic cells and reproductive cells, emphasizing their role in making up the structure and function of the organism outside of reproductive systems.
