Somatic cells are the body cells that make up most of an organism's tissues and organs, excluding the reproductive cells. They contain a full set of chromosomes, which carry the genetic information necessary for growth, development, and functioning. In humans, somatic cells are diploid, meaning they have two sets of chromosomes, one from each parent. These cells undergo processes like mitosis for growth and repair. Unlike germ cells, which are involved in reproduction and carry only half the genetic material, somatic cells are responsible for the everyday functions of the body. Examples of somatic cells include skin cells, muscle cells, and nerve cells.
