TEKS 5A Review Questions (Cell Cycle)
1. How do cells grow? What are some things that become problematic to a cell that gets too big?
2. What is cell division? What happens when a cell divides?
3. What is the cell cycle? Why is it important?
4. Human cells have 23 pairs of chromosomes. After cell division, how many pairs of chromosomes do each identical
daughter cell have?
5. What are the three main events of the cell cycle?
6. What happens during interphase? What are the three stages of interphase?
7. What happens during G1, S, and G2 of interphase?
8. What is mitosis (the definition)?
9. What are the four stages of mitosis given in the correct order (remember PMAT)?
10. What happens during prophase? Metaphase? Anaphase? Telophase? (Explain in terms of the chromosomes) Be able
to describe what is happening to the cell during each stage! Think of our song!!!
11. Draw a picture of a cell during Prophase, Metaphase, Anaphase, and Telophase. Be able to see a picture and know
what stage of the cell cycle the cell is in!!!
12. What is cytokinesis? Draw a picture of cytokinesis.
13. Which diagram most correctly represents the process of mitosis?
