2. Definitions
Mitosis-The process of the cell nucleus dividing to form 2 identical cells.
Interphase- First step in Mitosis/Meiosis. Chromosomes are extended and not visible. Chromosomes replicate. Centrioles replicate.

3. To do list . . . Finish notes on Mitosis
Work on Mitosis worksheet(HW if not completed in class)

4. Metaphase 2nd step in Mitosis
Chromatids (or pairs of chromosomes) attach to the spindle fibers.
They line up in the middle.
Centrioles
Spindle fibers

5. Metaphase Plant Cell Animal Cell
Photographs from:

6. Anaphase 3rd step in Mitosis
Chromatids (or pairs of chromosomes) separate and begin to move to opposite ends of the cell.
Centrioles
Spindle fibers

7. Anaphase Plant Cell Animal Cell
Photographs from:

8. Telophase 4th step in Mitosis
Two new nuclei form.
Chromosomes appear as chromatin (threads rather than rods).
Mitosis ends.
Cleaving begins.
Nuclei
Nuclei
Chromatin

9. Telophase Plant Cell Animal Cell
Photographs from:

10. Cytokinesis-occurs after mitosis
Cell membrane moves inward to create two daughter cells
each with its own nucleus with identical chromosomes.
