Correct Answer: Cell division
Subject: 2025
Explanation: <p><strong>Key Fact:</strong> <strong>Cell division</strong> is the fundamental biological process by which a parent cell duplicates its genetic material and divides to produce two daughter cells (mitosis) or four genetically distinct haploid daughter cells (meiosis).</p><p><strong>Additional Info:</strong> Mitosis is responsible for somatic tissue growth, regeneration, and asexual reproduction, maintaining chromosome number ($2n \rightarrow 2n$). Meiosis takes place in germ cells to produce haploid gametes ($2n \rightarrow n$) for sexual reproduction. Rudolf Virchow famously encapsulated this in 1855: <em>'Omnis cellula e cellula'</em> (All cells arise from pre-existing cells).</p><p><strong>Why the other options are wrong:</strong> Cell respiration is the biochemical breakdown of glucose to release ATP; Cell synthesis refers to anabolic production of biomolecules; Cell fermentation is anaerobic glycolysis.</p><p><strong>Exam Trick:</strong> Parent cell $\rightarrow$ Daughter cells = Cell Division.</p><p><strong>Final Answer:</strong> Cell division</p>
