Answer: Apoptosis.
- A Mitosis
- B Necrosis
- C Apoptosis
- D Cytokinesis
Correct answer: C. Apoptosis
Explanation: Apoptosis is programmed cell death: an orderly process by which cells self-destruct when they are damaged or no longer needed.
The cell cycle: G1 (growth and preparation), S (DNA replication, chromosome number stays 2n but DNA content doubles), G2 (final checks before division), and M (mitosis itself) - together, G1+S+G2 make up interphase.
Concept context
Mitosis and meiosis: how cells divide for growth, repair, and reproduction.
