03.01 Cell Cycle & Mitosis
Transcript of 03.01 Cell Cycle & Mitosis
Always handle microscopes and glass slides carefully.
Wash your hands after handling the prepared specimans
Data and observations
Based on your data, what can you infer about the length if the time spent in each of the cell cycle?
If your observation had not been restricted to the tip of the onion root, how would the rusults be different?
All of the cells would have probably been in interphase.

Understand and identify the stage of the cell cycle and mitosis.
Apply and analytical technique to estimate the relative legnth of each stage of the cell cycle.
I predict that there will be more cells in metaphase than in any other phase.
Number of cells
in part 1
I can infer that the cells spend most of the time in interphase and spends less time in in each stage as the cycle continues.
What stages were the longest and the shortest?
The longest stage is interphase, with anaphase being the shortest becuase it doesnt last very long.
What is a distinguishing visisble feature of each stage of the cycle?
The position of the chromosomes
What differences can you see when you compare the nucleus of a dividing cell with that of a nondividing cell?
the chromosomes are visible when a cell is dividing as oppose to nondividing cells.
