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?

description of cell
interphase
the cell is alone somewhere usally in the middle.
prophase
the cell is alone but with marks on it.
metaphase
the cell only has marks in the middle.
anaphase
the cell has marks on only the top and bottom of itself.
telophase
there’s two parts with marks.
cytokinesis
there are two parts that are divided with a line they also have marks.
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 the precentage of the cell cycle spent in each stage

part 2: using your percentages in part 1 create a chart 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:
be sure to answer the following reflection questions as a summary in the conclusion of your lab report:
was your hypothesis correct? why or why not?
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.

questions:
using what you have learned in the lesson and the virtual lab activity, answer the following questions in complete sentences.
what differences can you see when you compare the nucleus of a dividing cell with that of a non-dividing cell?
if your observation had not been restricted to the tip of the onion root, how would the results be different?
