Extra Credit Essay Questions: REMEMBER TO WRITE IN ESSAY FORM!

1. Compare and contrast photosynthesis and cellular respiration. You must describe at least five ways that

    they are similar or different. Give plenty of details and be sure to write in paragraph form.

2. Choose either photosynthesis or respiration and describe the process fully. If you choose

    photosynthesis, you must describe the two main reactions completely. If you describe cellular

    respiration, you must describe the three main reactions completely. Be sure to tell me for either one:

    Where does the reaction occur? What do you start with? What do you produce? And give details!
