Introduction: Find out the difference between Cytokinesis and Mitosis.  How do they go together in order to complete the cell division process?  


Part 1: 
Can you find dividing cells in the onion root tip?
Yes, we can see cells in every phase of the cell cycle.

What differences can you see when you compare the nucleus of a dividing cell with that of a 
non-dividing cell? 
In a non-dividing cell, we can clearly see the nucleus whereas in other stages we see it less clearly or we can't see it at all


Part 2: View a video of mitosis in an animal cell.

Part 3: Identify at least one cell in each of the stages of division summarized in the review. Place the cursor over a dividing cell and click once. Identify the stage of division. When you have identified at least one cell in each stage, proceed to the next section.

Part 4: See what differences you can detect between the division of an animal cell and a plant cell.
