The process of cell division that results in two identical diploid daughter cells for growth and tissue repair is called?

• A. Mitosis
• B. Meiosis
• C. Cytokinesis
• D. Binary fission

Answer: (A)

Mitosis is the division of a cell’s nucleus that produces two genetically identical diploid daughter cells, which is essential for growth and tissue repair. In mitosis, the cell duplicates its chromosomes and evenly distributes them into two new nuclei, so the chromosome number stays diploid in each daughter cell. This genetic sameness is what makes mitosis ideal for replacing old or damaged cells in multicellular organisms. After the nuclear division, cytokinesis splits the cytoplasm, resulting in two separate, identical cells.

In contrast, meiosis creates gametes with half the chromosome number and introduces variation, while binary fission is how some single-celled organisms reproduce and also yields two identical cells but in a different cellular context.
