1. Cell Division: Mitosis

2. Objective: Understand the purpose of mitosis
Understand the process of mitosis
Explain the sequence and events of each phase

3. Review:

4. What are the two types of cells?
Eukaryotic
Prokaryotic

5. What are prokaryotic cells?
Simple cells
Few internal structures
No membrane bound organelles
One-celled organisms, Bacteria

6. Examples of prokaryotic cell:
Bacteria
Cells

7. What are eukaryotic cells?
Cells that contain organelles surrounded by membranes
Most living organisms

8. Examples of eukaryotic cells:
Plant
Cells
Animal
Cells
Human
Cells
Human
Cells

9. Plant Cell
(Tomato)
Animal Cell
(tiger)

10. How do prokaryotic cells divide?
Binary Fission
(A fancy name that scientists use to impress their girlfriends or boyfriends. A process where one prokaryotic cell becomes two.)

11. How do eukaryotic cells divide?
Mitosis!

12. Making more cells! What is mitosis? (How eukaryotic cells divide.)
A continuous process of four phases that results in the division of the nucleus.
Making more cells!

13. Why do we care? Once upon a time we were all one little cell.
Because of mitosis we are now made of trillions of cells.
This applies to animals too!

17. You get the idea…

18. The Phases of Mitosis

19. The 4 Phases of Mitosis:
Prophase
Metaphase
Anaphase
Telophase

20. What about Interphase?
Interphase is the resting period between cell division.

21. Why do we study diagrams first?
Easy to identify structures
Clear
Simple

22. Why do should we view microscopic images also?
To see the real deal!
To reveal greater complexities.

24. Are the cells really pink and purple?
Nope, they are stained so that we can see the organelles better.

29. They all look like blobs… how can we tell them apart?
