Somatic (body) cells, such as skin cells
B
Gametes (sperm and egg cells) during gamete production
C
Mature mammalian red blood cells, which lack a nucleus
D
Prokaryotic cells, which divide by binary fission
Verified step by step guidance1
Understand the definition of mitosis: Mitosis is a type of cell division that results in two genetically identical daughter cells, maintaining the same chromosome number as the original cell.
Identify the types of cells in multicellular eukaryotes: These include somatic (body) cells, gametes (sperm and egg cells), mature red blood cells, and prokaryotic cells (which are not eukaryotic).
Recall that somatic cells undergo mitosis to enable growth, tissue repair, and maintenance. Examples include skin cells, muscle cells, and liver cells.
Recognize that gametes are produced by meiosis, not mitosis, because meiosis reduces the chromosome number by half to maintain species chromosome number after fertilization.
Note that mature mammalian red blood cells lack a nucleus and therefore cannot undergo mitosis, and prokaryotic cells divide by binary fission, not mitosis.
