Cell Division Virtual Lab Activity
________________________________________
Instructions: The Virtual Cell Division Lab is on the lesson assessment page. On the image, it says “Click Anywhere to Start.” Follow the instructions as you move through the lab. The lab activity will keep count of your data on the right, and you can record this into the data table.
Title: Cell Cycle
Objective(s):
Hypothesis: I think ill get an even amount between them all.
Variables:
Data:
Record the number of cells you observed in the lab activity.
Stages Number of Cells
Interphase 34 cells
Prophase 8 cells
Metaphase 3 cells
Anaphase 2 cells
Telophase 2 cells
Cytokinesis 1 cell
Observations:
Record any observations about the cells you observed. What does the cell look like for each stage? What is a distinguishing visible feature of each stage of the cell cycle?
Stages Description of Cell
Interphase It looks like a wiggly shaped circle, and it has a bunch of squiggly lines in the middle of the circle.
Prophase It’s a circle, the outline of the circle are a bunch of parted lines and the inside it has a bunch of x shaped lines and a couple small squiggly lines.
Metaphase It’s a circle but not exactly a complete circle it has four x shaped lines in the idle of the circle.
Anaphase It’s a circle but not exactly a complete circle at the top it has four v shaped lines and the same thing for the bottom four v shaped lines at the bottom.
Telophase There are two circles, the outline of the circle are a bunch of parted lines, the two circles both have four v shaped lines in them and outside of the circles in between both of them they have small curved line connecting them and the circles are slightly slanted.
Cytokinesis I would say it is almost the exact same as Telophase but instead of it being slightly parted its completely straight.
Data Analysis:
Part 1: 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
Part 2: Using your percentages in part 1, create a graph that represents the time spent in each stage of the cell cycle.
Insert Chart [Hint: don’t forget to consider the relationship between your data and the type of chart to best represent your data]
Conclusion:
Include the following as a summary paragraph in the conclusion of your lab report:
• Analysis of the results of the experiment
o Based on your data, what can you infer about the length of time spent in each stage of the cell cycle?
o What stages were the longest and shortest? Give a brief explanation of why these stages may have that time period.
• Rationale for the support or rejection of the hypothesis
Questions:
Using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences.
1. What differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
2. If your observation had not been restricted to the tip of the onion root, how would the results be different?
