3. Mitosis vs. Meiosis Same copy Different copies Body Cell Sex Cell
Stomach cell Sperm Cell
Liver cell Egg cell

4. 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

5. Chromosomes*
= wound up DNA*
^^ Copy into journal!!!

6. Mitosis
What would happen if the DNA was not duplicated before the cell divides?

7. Mitosis Stages Interphase Prophase IPMATC Metaphase Anaphase Telophase

Animal Cell vs Plant Cell

9. Mitosis:
Meiosis
Cell division during SEXUAL reproduction. What do you notice that is different?

10. Crossing Over*
During Prophase 1 of Meiosis, homologous chromosomes pair up, cross arms, and swap genetic material (DNA)
Leads to variation among all sexually- reproduced organisms

12. Class Quiz: Mitosis or Meiosis?
Go down the line. Tell me WHY!
