Cell Membranes
QR Code Scavenger Hunt
FREE ACTIVITY
Requires use of an electronic device
with a QR scanner for each student
or student group.
Cell Membrane Scavenger Hunt
With your team use the following resources to answer the questions about the role of the cell
membrane. You will scan each QR code to find the resource. In some cases you might find parts
of an answer in multiple resources and the same resource might be useful for one or more
questions.
1. Define homeostasis:
2. Define dynamic equilibrium:
3. Define semi-permeable:
4. Describe the structure AND identify the function of the following molecules in a cell
membrane:
a. Carbohydrate:
b. Cholesterol:
c. Integral (transport) protein:
d. Peripheral Protein:
e. Phospholipids
5. Why is the phrase “fluid mosaic model” an accurate description of the cell membrane?
6. What types of molecules are able to pass through a membrane?
7. Why types of molecules are not able to pass through a membrane?
8. List TWO other interesting facts that you learned from any of the resources.
9. Conclusions: Write a detailed paragraph explaining the role a cell membrane plays in
maintaining homeostasis within a cell. Use details and examples from the scavenger hunt
to support your ideas. How is this related to our research on celery?
Thank you for checking out this FREE product from my store. Even though you don’t earn TpT credits for
feedback on free items I still greatly appreciate your feedback and rating.
This item is the first in what I hope to make a paid bundle of QR scavenger hunts for different biology
topics. Please let me know what you think about this resource, if you have ideas or suggestions, or if
there is a specific biology topic you would like to see in this format in the future please contact me at
