Cell Cycle Lab Report
Instructions: For this lab activity, you will examine a section of an onion root tip under a
compound light microscope to determine the approximate amount of time spent in each stage of
a cell’s life cycle. At the end of your lab activity, you will complete chi-square testing using some
of your data. Submit your lab report to your instructor when completed.

Title: Cell Cycle and Its Stages
Objective(s): Examine a section of an onion root tip under a compound light microscope to
determine the approximate amount of time spent in each stage of a cell’s life cycle.
Hypothesis:
Write a hypothesis, using an if/then statement, to predict the stage in which a cell spends most of
its time.
I predict that the onion root cell cycle will spend more time in the interphase, due to this being
the preparation part of the cell cycle. If we examine and time the different stages, the stages
within the interphase will have a higher time.
Procedure:
Access the virtual lab and complete both examinations of onion root tip cells. The materials are
listed for you. However, you are responsible for providing a brief summary of the steps you
followed during the experimental procedure.
Materials:
Cell Cycle Virtual Lab
Summary of Steps:
1. In this laboratory activity, you will be examining a section of an onion root tip under
a compound light microscope.
2. These slides were prepared by slicing the roots into thin sections, mounting them on
glass microscope slides, staining so that the chromosomes are more visible, and then
covering the specimen with a cover slip.
