About this resource

This quiz focuses on the cell cycle, a fundamental concept in cell biology that examines the phases cells undergo during growth and division. Appropriate for 9th grade biology students, the questions assess understanding of the four main phases of the cell cycle: Gap 1 (G1), Synthesis (S), Gap 2 (G2), and Mitosis (M). Students need to comprehend that cells spend different amounts of time in each phase, with G1 typically being the longest phase where cells grow in size and prepare for DNA replication. The quiz requires students to analyze models and diagrams to understand how cancer affects cell cycle timing, making cells divide more rapidly and remain smaller than normal. Students must also grasp the relationship between phase duration and the probability of observing cells in different phases under a microscope, as well as understand how external factors like ultraviolet light can damage cells during specific phases of the cycle. Created by Rebecca Gutierrez, a Science teacher in the US who teaches grade 9. This POGIL (Process Oriented Guided Inquiry Learning) quiz serves as an excellent tool for reinforcing cell cycle concepts through guided inquiry and model-based reasoning. Teachers can use this assessment as a follow-up activity after introducing the cell cycle, allowing students to work collaboratively to analyze data and draw conclusions about cellular processes. The quiz works effectively as a formative assessment to gauge student understanding before moving to more complex topics like cell cycle regulation and cancer biology. It can also serve as homework to reinforce classroom learning or as a review activity before unit tests. The questions align with NGSS standard HS-LS1-4, which requires students to use representations to illustrate how DNA in the nucleus provides instructions for characteristic traits through protein synthesis, and supports understanding of cell division processes essential for growth and repair.

The Cell Cycle POGIL

7 questions

How many phases are in the cell cycle as shown in the diagram in Model 1?

During which phase does the size of the cell increase?

Cancerous tumors often consist of many cells that are much smaller than normal. According to Model 1, what part(s) of the cell cycle is (are) most likely being affected?

In Model 1, if the length of the arrow represents time, what happens to the time necessary for the cell cycle in cancerous cells?

Looking at the third column of Model 2, compare the time spent in mitosis with the time spent in gap 1 in human cells. What is the difference?

Imagine 100 cells were chosen randomly from a tissue sample and examined under a microscope. In which phase of the cell cycle would you expect to find the largest number of cells?

According to Model 3, ultraviolet light is affecting a cell in which phase of the cell cycle?
