Cellular Respiration and Photosynthesis Worksheet

Cellular Respiration and Photosynthesis Worksheet

 

Directions: Complete this worksheet and submit it to Blackboard on the due date listed. Total Points Possible: 102/100

 

Introduction:

Cellular respiration and photosynthesis are both metabolic pathways. These pathways have a lot in common, but they are also used for different things. Now that you have learned about both pathways, your job is to compare and contrast them. Venn diagrams are a great way to organize data and information so you can see connections between them. Your goal is to organize characteristics of cellular respiration and photosynthesis, analyze those characteristics, and draw conclusions about the similarities and differences between the two pathways.

 

Tasks to complete:

• All scientific investigations start with identifying a question. What question do you want to know about cellular respiration and photosynthesis that can be answered by a Venn diagram? (10 points)

 

 

 

• Organize your information. Using a Venn Diagram (on the next page), organize the following terms as being a characteristic of cellular respiration, photosynthesis, or both. Each correctly placed word is worth 2 points. (62 points total)
