Question

Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
What stages were the longest and shortest?
Give a brief explanation of why these stages may have that time period.
What is a distinguishing visible feature of each stage of the cell cycle?
What differences can you see when you compare the nucleus of a dividing cell with that of a nondividing cell?
If your observation had not been restricted to the tip of the onion root, how would the results be different?

Answer 1

1. Most of the time in the cell cycle is used in the interphase.

2. As we know, interphase was the most time spent while the second is in the prophase. This is because this is the process of separating genetic material.

3. They all have visible chromosomes. Every phase has numerous of them.

4. The only differences is that chromosomes are only of that dividing cells.

5. I believe that there would be more chromosomes shown if the observation had not been restricted.
