Detailed explanation-1: -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-2: -In multicellular plants and animals, however, meiosis is restricted to the germ cells, where it is key to sexual reproduction. Whereas somatic cells undergo mitosis to proliferate, the germ cells undergo meiosis to produce haploid gametes (the sperm and the egg).

Detailed explanation-3: -It occurs in somatic cells of the body. The formation of somatic cells is mediated by mitosis and hence, mitosis is also known as somatic cell division. Karyokinesis and cytokinesis are two steps of mitosis.

Detailed explanation-4: -Answer and Explanation: Somatic cells divide by mitosis in order to produce daughter cells that are identical copies of the parent cell. Mitosis is the process of cell division in eukaryotic cells. Prior to mitosis the DNA is duplicated and then the chromosomes are split equally into two daughter cells.

Detailed explanation-5: -So, the correct statement is ‘Mitosis takes place regularly in somatic cells, whereas meiosis occurs only in germ cells’.
