Communicate our knowledge of each phase of cellular division. 2. Explain why it is important for the cell cycle to be strictly controlled.

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?

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

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.

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

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

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

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?

Lesson 53: Mitosis Buffalo Case Study Day 1- Mitosis DO NOW: (5 minutes) Why are checkpoints important for organisms? How does the body respond if the chromosomes are copied incorrectly during cell division? HOMEWORK: Complete Cell Cycle Concept Map Packet by Wednesday Study for Quiz Thursday on Cell Cycle and Mitosis After School: Tuesday-Thursday It is YOUR responsibility to make up missed classwork/labs Today’s Plan: Do Now 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.

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.

Lesson 55: Mitosis and Cell Cycle Quiz DO NOW: (5 minutes) What are the 4 phases of mitosis? 2. Why did we use an onion root tip to study mitosis? HOMEWORK: Read and take notes on textbook page 275-278 Reading check tomorrow! Today’s Plan: Do Now Cell Cycle and Mitosis Quiz Closure OBJECTIVE: We will learn to 1. Communicate our knowledge of the cell cycle and mitosis by taking a summative assessment.
