Whitefish Blastula Cell Evaluation

Evaluation:
The graph that was produced shows that Whitefish Blastula cells spend the most amount of time in interphase followed by prophase, metaphase, anaphase and finally telophase. Relative time was found by finding the total number of cells in each phase and then dividing it by the total number of all cells counted and finally multiplying by 100. Doing this showed that the cell that takes up the most amount of time is interphase at 71.35%. Although I was unable to confirm the accuracy of the relative times found in the experiment because there was no information available the time taken in interphase compared to the other cells is probably correct. This is because in interphase a cell must grow and duplicate its chromosomes which takes a long time. The other times are also probably accurate because in phases like telophase and anaphase the cell simply splits and does not need to grow or change. The data that was collected is not reliable. …show more content…
Each person would classify the “in-between” cells the same way to make their own trials more reliable. Even though individually each person was not making an error with their counting and classifying when the data was put together the differences in perspective would cause a source of error. This is a source of error because different people will have different interpretations of cells that are not obviously in one phase. Even if they counted the cells accurately every person would have a different interpretation of what phase cell was in causing discrepancies in the data. An example of this is the data collector EC who observed a higher number cells in telophase than any other person. This is most likely because they had a different interpretation of what telophase looked like. This would affect the reliability because it would result in there being differences between each person’s
