Verified step by step guidance

Understand the definitions of mitosis and meiosis: Mitosis is the process of cell division that results in two identical daughter cells, typically occurring in somatic (body) cells. Meiosis, on the other hand, is a specialized form of cell division that reduces the chromosome number by half, producing gametes (sperm and egg cells) in germ cells.
Review the types of cells involved: Somatic cells are all the cells in the body except for reproductive cells, while germ cells are the cells that give rise to gametes through meiosis.
Analyze the options provided: The first option, 'somatic; germ,' aligns with the fact that mitosis occurs in somatic cells and meiosis occurs in germ cells. The other options do not correctly describe the processes or cell types involved.
Eliminate incorrect options: 'Prokaryotic; eukaryotic' is incorrect because mitosis and meiosis only occur in eukaryotic cells, not prokaryotic cells. 'Haploid; diploid' is incorrect because mitosis can occur in both haploid and diploid cells, and meiosis specifically reduces diploid cells to haploid gametes. 'Germ; somatic' is incorrect because germ cells undergo meiosis, not mitosis.
Conclude that the correct answer is 'somatic; germ,' as mitosis occurs in somatic cells and meiosis occurs in germ cells.
