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. Procedure Data and Observations Fill in the data table containing a tally of the number of cells observed in each of the following stages StageNumber of Cells in Part 1
Number of Cells in Part 2InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesis
Record any observations about the cells you observed (what does the cell look like for each stage) StageObservations Part 1
Observations in Part 2InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesis Data Analysis Calculate the percentage of the cell cycle spent in each stage. Number of cells in given stage total number of cells counted 100 of the cell cycle spent in this stage StagePercentage of Cells Part 1
Percentage of Cells in Part 2InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesis Create a graph that represents the time spent in each stage of the cell cycle. (you may place the graph here or submit as a separate attachment) Conclusion Be sure to answer the following reflection questions in the conclusion of your lab report Based on your data, what can you infer about the length of time spent in each stage of the cell cycle Hint An inference is what you are able to conclude based on the data, facts or observations. StageBased on my data and length of time spent in this stage, I can infer
InterphaseProphaseMetaphaseAnaphaseTelophaseCytokinesis What stages were the longest and shortest Give a brief explanation of why these stages may have that time period. The longest stage is .. The shortest stage is .. I believe the reason for this is .. What is a distinguishing visible feature of each stage of the cell cycle StageA distinguishing visible feature for this stage is
