Mitotic Cells Questions

Part I
1. Why were plants root tip cells used for viewing cell division?
2. If you were to observe cell division of animals, what specific type of animal cells would you use? Wxplain your reasons.
3. How would cell division in plant cells differ from that of animal cells? Use a Venn diagram organize you response.
4. At what stage of mitosis is it easiest to determine the kind and number of chromosomes? Explain your reasons.
5. What evidence did you observe that shows mitosis is a continuous process, not a series of separate events?
6. What specific process in mitosis ensures that the normal number of chromosomes is restored after each cell division? Explain your response.

Conclude
1. The number of animal cells in each phase of mitosis is recorded in the table below. If the time taken to complete on cycle of mitosis was 1h, create a cell-division clock to represent the data.
2. Do your observations on onion root tip cells indicate that there were more cells in some phases than in others? Identify the most common phase/s and explain what these differences in numbers might mean.
