An Introduction to Photosynthesis and Cellular Respiration
Directions: Don’t write on this! Don’t even think about it. I see you thinking about it. Don’t do it.
Record the answers in your notebook with a heading that is the same as the one on this page. You
should write in COMPLETE sentences because it will make your English teachers proud (and because
that’s what I’m asking you to do). Happy learning!
Example of writing a complete sentence from the question:
Q – Who is your favorite teacher ever in life?
A – My favorite teacher ever in life is Mrs. G.
