Which statement is true about somatic cells?

Somatic cells are indeed characterized by containing a full set of chromosomes, which in humans amounts to 46 chromosomes arranged in 23 pairs. This full set includes both autosomes and sex chromosomes. Somatic cells are responsible for the majority of the body's functions, including growth, repair, and maintenance of tissues and organs. They differentiate into various cell types that form the different organs and tissues of the body.

In contrast to somatic cells, germ cells are haploid, meaning they contain only one set of chromosomes, and they are involved in reproduction. Additionally, while somatic cells undergo division through mitosis allowing them to grow and replace dead or damaged cells, meiosis is a process specific to the formation of gametes (sperm and egg cells). Therefore, the statement about somatic cells containing a complete set of chromosomes and being responsible for body functions is the accurate one.
