3. BINDER QUIZ  7 MINUTES  5 QUESTIONS

4. WORK SESSION Guided Notes Mitosis

5. How do prokaryotic cells divide? 1. Prokaryotic cells are simple so they undergo a simple process called binary fission. 2. They just grow longer and longer until they separate into two identical cells

6. How do eukaryotic cells divide? Cell Cycle!

7. Cell Cycle and Mitotic Division Objectives:  Name the differences between prokaryotic and eukaryotic cells.  Summarize the role of cell organelles (nucleus, nucleolus, centriole) in eukaryotic cell reproduction (mitosis).  Summarize the phases of cell reproduction (mitosis).

8. The Cell Cycle 1. Purpose: to replace dead or dying cells, to allow an organism to grow and develop 2. Eukaryotic cells grow until they reach their size limit 3. Three major parts: interphase, mitosis, and cytokinesis.

9. REMEMBER THIS!! 1. One cell enters mitosis, two cells exit. 2. The two cells produced are identical to the original cell. Knowing this…under what type of reproduction would you classify mitosis?

10. Part 1: Interphase 1. Occurs before mitosis 2. The cell spends most of its time in interphase (G1,S, and G2). 3. Cell is growing and DNA is replicating. 4. Chromatin is loose 5. Chromosomes are not visible.

11. Part 1: Interphase  3 Stages –G1 – Cell grows gets larger –S – DNA synthesis –G2 – Cell synthesizes proteins and keeps growing

12. Part 2: Mitosis 1. Mitosis occurs in order for organisms to grow and develop. 2. There are 4 main stages: Prophase, Metaphase, Anaphase, Telophase. Take 2 minutes and come up with a way for you to remember the order of the mitotic phases.

13. Mitosis: Prophase 1. Chromatin condense into chromosomes we can see. 2. Nuclear membrane breaks down in order to allow free movement of the DNA. 3. Nucleolus disappears 4. Centrioles migrate to poles and mitotic spindle begins to form

14. Brain teaser… 1. What is this a picture of? 2. In what specific cell organelle is it found?

16. Mitotic Spindle copyright cmassengale

17. Mitosis: Metaphase 1. “Meta-” means “middle” 2. Mitotic spindle fibers attach to chromosomes 3. Chromosomes line up in the middle of the cell

18. Mitosis: Anaphase 1. Mitotic spindle fibers shorten 2. Sister chromatids separate and are pulled towards opposite sides of the cell

19. Mitosis: Telophase 1. “Telo-” means “distant” or “end” 2. Chromatids reach the opposite ends of the cell 3. Chromosomes now uncoil becoming less visible 4. Nuclear membrane reforms and surrounds the chromosomes

20. Part 3: Cytokinesis 1. Plant cells: Cell plate forms at center of cell 2. Animal cells: Cleavage furrow forms at center of cell 3. Cell cytoplasm and all its contents divided into 2 daughter cells

21. Overview Cell Cycle

22. Summary: In your own words  Why is cell reproduction important?

23. WHITEBOARD CHECK NAME THAT STAGE Checkpoint!!

24. What stage is this? TELOPHASE

25. What stage is this? CYTOKINESIS

26. What stage is this?  The stage in which the mitotic spindle fibers shorten and chromosomes begin to move to the opposite ends of the cell is called…. ANAPHASE

27. What stage is this? Interphase

28. What stage is this? METAPHASE

29. What stage is this?  The longest stage of the cell cycle in which the cell grows and DNA is synthesized is called… Interphase

30. STARTER Take out your homework at your seat: The Cell Cycle Review, turn in progress reports to basket. 1. Place these phases in the correct order: Prophase, Telophase, Interphase, Anaphase, Metaphase, Cytokinesis 2. Which phase of the cell cycle are chromosomes lined up on the equator of the cell? 3. During which phase of the cell cycle is the cell replicating DNA and preparing for cell division? 4. During which phase of the cell cycle does the cell split into two daughter cells? 5. During which phase of the cell cycle are the chromatids separated?
