Hypothesis: What do you predict you will find about the number of cells in each of the phases of the cell cycle? Provide an explanation for your prediction. Procedure: Data and Observations: Create a data table containing a tally of the number of cells observed in each of the following stages: StageNumber of Cells in Part 1Number of Cells in Part 2 Interphase Prophase Metaphase Anaphase Telophase Cytokinesis Record any observations about the cells you observed (what does the cell look like for each stage): 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 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: 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? How to cite 3. 01 Cell Cycle Lab Report Safety Notes, Essay examples
