Cell Cycle

• Interphase: G1 (growth), S (DNA replication), G2 (preparation).
• M phase: mitosis + cytokinesis.

Mitosis

• Prophase → Metaphase → Anaphase → Telophase.
• Produces 2 identical diploid cells; growth/repair.

Meiosis

• Meiosis I: reductional, crossing over in prophase I.
• Meiosis II: equational.
• Produces 4 variable haploid cells; sexual reproduction.

One-Line Summary

The cell cycle regulates growth and division through interphase and M phase, with mitosis producing identical diploid cells for growth/repair and meiosis producing genetically variable haploid gametes essential for sexual reproduction.
