Mitosis Web Quest Part 1
Closure
OBJECTIVE: We will learn to
1. Communicate our knowledge of each phase of cellular division.
2. Explain why it is important for the cell cycle to be strictly controlled.

2. Closure
Why is it important for the cell cycle to be strictly controlled?
If damaged cells are not repaired, what happens to them?
What problem can develop if the cell cycle is not controlled?

4. Lesson 52: Mitosis Web Quest Day 2

Closure
OBJECTIVE: We will learn to
1. Communicate our knowledge of each phase of cellular division.
2. Explain why it is important for the cell cycle to be strictly controlled.

5. Do Now Why are there many checkpoints in the cell cycle?
To ensure that cells are made normally
If all checkpoints fail, tumors can result

6. Control of the Cell Cycle Internet Activity
G1- Makes the decision if the cell should divide, delay division, or enter resting stage.
G2- Check the success of DNA replication and begin mitosis
M- Triggers the exit from mitosis and cytokinesis. Begins G1.
2. Cdk- carry the cell past the checkpoint and into mitosis
Cyclin- tells the cell when it is time to start/stop the cell cycle
When the level of MPF is high enough the G2 phase ends and mitosis begins. It also destroys cyclin.

7. To replace dead or injured cells. Development of a fertilized egg.
300 million
Skin cells- very often
Liver cells- sometimes
Bone marrow- continuously
Stomach lining- continuously

8. 4. When a cell dies, it breaks up and leaves an empty space in the tissue 5. CDK Cyclin

9. 7. Checkpoint 1- the end of G1 Checkpoint 2- during S phase Checkpoint 3- during M phase 8. So that the daughter cells produced are exact copies of the mother cell 9. Changes in the chromosomes (mutations) 10. Cells may become cancer cells, which have altered chromosome

10. Closure
Why is it important for the cell cycle to be strictly controlled?
If damaged cells are not repaired, what happens to them?
What problem can develop if the cell cycle is not controlled?

Buffalo Case Study Part 1
Closure
OBJECTIVE: We will learn to
Communicate our knowledge of each phase of cellular division.
Explain the difference between cell division of prokaryotic and eukaryotic cells.

12. Closure
What are the major events that occur during each of the stages in the life cycle of a cell such as a skin cell, i.e., Interphase, Prophase, Metaphase, Anaphase, Telophase, and Cytokinesis? Assume you are a court reporter that has to explain these stages to your readers with as little jargon as possible.
How does cell division differ in prokaryotes and eukaryotes? Clearly, these differences may be difficult for the prokaryotes in the jury to follow unless you show the similarities and differences.
