Advantages of Sexual Reproduction
Brief discussion

5. Review Packet
Take 10 minutes and review answers with your partners. If you have not finished, pick up where you left off and then go back to the beginning.
You have 10 minutes

6. The Cell Cycle What did you notice? Answers for A-D
Use graphic organizer for interpreting visuals

7. The Cell Cycle Now answer E & F using the handout
Page one of The Cell Cycle handout

9. Pre-assign numbers 1-5 to each table… Students discuss in pairs.
Think: Cell Processes
1) Why do cells divide?
2) Which cells in the body divide more frequently?
3) Which cells in the body divide less frequently?
4) What stage are they in if they are not dividing?
5) Which cell division process creates IDENTICAL cell copies?
6) Which cell division process creates UNIQUE cell copies?
So organisms can grow and repair!
Skin cells
Brain/nerve cells G0
Mitosis
Meiosis

10. Cell Cycle & Cancer
Cancerous lung cells
Cancer occurs when cells do not receive proper signaling
“Messed up” cells are normally stopped at the checkpoints
“Messed up” cells are told to die- known as apoptosis (programmed cell death)**
Cancer occurs when cells fail to go through apoptosis, and continue dividing anyway

15. Cell Pictures/Labeling
You need to draw how the cell looks for EACH stage of mitosis
You must LABEL the parts of the cell
However, for each additional picture, you only need to label the NEW structures
Draw example drawing

16. Chromatin is NOT condensed into chromosomes yet (can’t see it)
Interphase*
NOT part of mitosis (precedes mitosis)
Includes stages G1, S, G2
Cellular contents (organelles) copied
Genetic material (chromatin) copied
Checked for mistakes
Chromatin is NOT condensed into chromosomes yet (can’t see it)
Stages from:

17. Prophase Prophase* d Early Prophase Late Prophase
Chromatin condenses into chromosomes (now visible)
Nucleolus disappears
Nuclear envelope breaks down
Two centrosomes form; create mitotic spindle
Prophase*

18. Metaphase* Easiest stage to identify Chromosomes align down the middle
Known as the “metaphase plate”
Microtubules attach to centromeres of sister chromatids

19. Anaphase* Early Anaphase Late Anaphase
Microtubules pull sister chromatids apart (centromeres split)
Individual chromosomes are pulled by the microtubules to opposite poles (same amount of genetic material on either side)
Anaphase*

20. Telophase* Begins after chromosomes stop moving
“Reverse of prophase”
Begins after chromosomes stop moving
Spindle fibers dissolve
Chromosomes uncoil and revert to chromatin form
A new nuclear envelop forms around each chromatin mass (forms nucleus)
Nucleoli appear
Cleavage furrow forms at site of metaphase plate (middle)

21. Cytokinesis*
Cytoplasm pinches inward (at the cleavage furrow) until cell is divided into two identical daughter cells
Organelles reappear
Both cells can now start the process again…

22. Interphase (Begins Again)d

23. Animal Cell vs. Plant Cell

24. Identify the stages! Pick people to come up.

25. Exit Ticket: Identifying Stages of Mitosis
What’s an easy way to remember the stages?
