Detailed explanation-1: -Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).
Detailed explanation-2: -Mitosis occurs in somatic cells; this means that it takes place in all types of cells that are not involved in the production of gametes. Prior to each mitotic division, a copy of every chromosome is created; thus, following division, a complete set of chromosomes is found in the nucleus of each new cell.
Detailed explanation-3: -Meiosis is a specialized form of cell division that produces reproductive cells, such as plant and fungal spores and sperm and egg cells. In general, this process involves a “parent” cell splitting into two or more “daughter” cells.
Detailed explanation-4: -Sex cells are the haploid cells formed from the meiotic division of germ-line cells that occur in the primary sex organs. The testes produce sperm cells and the ovaries produce egg cells.
