Answer: Production of gametes (sex cells).
- A Growth and repair
- B Production of gametes (sex cells)
- C Replacement of damaged cells
- D All cell divisions
Correct answer: B. Production of gametes (sex cells)
Explanation: Meiosis produces gametes (sperm and eggs) with half the chromosome number, enabling sexual reproduction.
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.
