3.01 Cell Cycle Lab Report
Safety Notes:
* Always handle microscopes and glass slides carefully.
* Wash your hands after handling the prepared specimens.
Materials:
* Compound light microscope
* Glass microscope slide with prepared onion root tip specimen Purpose:
* understand and identify the stages of the cell cycle and mitosis. * apply an analytical technique to estimate the relative length of each stage of the cell cycle. Hypothesis Procedure:
I predict that all cells somatic will suffer all the division of mitosis multiple times in their lifetime; the product would be able to see the chromosomes in a stage of mitosis. It is predicted that the cells won’t be seen clears or big enough, but is going to give ideas or example how’s the experiment is going. Data and Observations:

Create a data table containing a tally of the number of cells observed in each of the following stages: Stage| Number of Cells in Part 1| Number of Cells in Part 2| Interphase|  34|  49|
Prophase|  8|  13|
Metaphase|  3|  4|
Anaphase|  2|  3|
Telophase|  2|  4|
Cytokinesis|  2|  3|
Record any observations about the cells you observed (what does the cell look like for each stage): Data Analysis:

Percent of total cells in part 1| Percent of total cells in part 2| 34/20 x100=170%| 49/20 x100=245%|
8/20 x100=40%| 13/20 x100=65%|
3/20 x100=15%| 4/20 x100=20%|
2/20 x100=10%| 3/20 x100=15%|
2/20 x100=10%| 4/20 x100=20%|
2/20 x100=10%| 3/20 x100=15%|
255%| 380%|

Create a graph that represents the time spent in each stage of the cell cycle. Conclusion:
Be sure to answer the following reflection questions in the conclusion of your lab report: 1. Based on your data, what can you infer about the length of time spent in each stage of the cell cycle? That in part 1 it can out 255 percent and part 2 was 380 percent 2. What stages were the longest and shortest?...
