Chapter 4 – Section 3 – The Cell Cycle – pages 98 - 101
The Life of a Cell
1. What is the cell cycle? When does it begin and end?
2. What does a cell need to do before it duplicates?
3. What is DNA? What are chromosomes? How are they related?
4. What is the difference between prokaryotic and eukaryotic cells?
Making More Prokaryotic Cells
1. Bacteria are an example of a prokaryotic cell. What organelles do they have? What do they
not have?
2. How do they reproduce?
Eukaryotic Cells and Their DNA
1. True or
False
Prokaryotic cells are more complex than eukaryotic cells.
2. True or
False
More complex eukaryotic cells have more DNA than less complex
eukaryotic cells.
3. How many total chromosomes are found in most cells in the human body?
4. How many pairs of chromosomes are found in most cells in the human body?
5. What are homologous chromosomes?
Making More Eukaryotic Cells
1. What happens during interphase? What is a chromatid? What is a centomere?
2. Describe what happens during each phase of mitosis.
3. What does mitosis guarantee?
4. Why is it important for chromosomes to be copied before cell division?
5. What happens during the last stage?
6. How does mitosis ensure that a new cell is just like its parent cell?
7. Cell A takes 6 hours to complete a division. Cell B takes 8 hours to complete a division. After
24 hours how many more copies of Cell A would there be than Cell B?
Cytokinesis
1. What is cytokinesis?
2. How is cytokinesis different in cells that have a cell wall?
3. What would happen if cytokinesis occurred without mitosis?
