Cell Division and Mitosis

This lesson covers the biological process of cell division by mitosis. Students will learn about the cell cycle, why DNA replication is essential, and how one parent cell produces two genetically identical daughter cells for growth and repair.

Learning objectives

  • Define the cell cycle and identify the three main stages.
  • Describe the process of mitosis and its importance in growth and repair.
  • Explain why DNA replication must occur before a cell divides.

Core worksheet (first questions)

  1. What two things must a cell do during the first stage of the cell cycle before it can divide?
  2. Why is it important that the DNA is replicated before division?
  3. Describe what happens to the chromosomes during the mitosis stage.
  4. How do the daughter cells compare genetically to the parent cell?
