Photosynthesis and Cellular Respiration Review
Name:
Period:
For the topic of Photosynthesis, if you are a #1 your role is to share what you know for each of the components
of Photosynthesis listed below. If you are a #2 you are to listen to what is shared with you and agree with it or
make any corrections or additions to the information. For the topic of Cellular Respiration, the #1 and #2 will
switch roles. All students should be prepared to share their answers with the class at any point in the
discussion, regardless of their role during that part of the activity.
Photosynthsis:
1) Why do organisms carry out photosynthesis?
2) Write out the overall chemical equation for photosynthesis. Identify where each of the reactants come
from.
3) In which organelle does photosynthesis take place?
4) What types of organisms undergo photosynthesis?
5) What is a waste product of Photosynthesis?
6) What other structure(s) are important to maintaining homeostasis in organisms that carry out
photosynthesis? Explain how they function to help maintain homeostasis.
