Mitosis results in daughter cells with the same chromosome number as the parent cell.

• A. True
• B. False
• C. Only in plants
• D. Only in animals

Answer: (A)

Mitosis maintains the chromosome number from parent to daughter cells. Before division, DNA is replicated, producing two sister chromatids for each chromosome. As mitosis proceeds, the sister chromatids separate and are distributed to opposite daughter nuclei. The result is two daughter cells that contain the same number of chromosomes as the parent cell (for a typical diploid organism, the same 46 in humans), though each chromosome is now a single chromatid. This is distinct from meiosis, which halts the chromosome number by half to form gametes. The statement holds true across plant and animal cells, so it accurately describes mitosis.
