This is a PPT on cell respiration - it is approximately 10 slides, which includes a review on the last 2 slides. I teach this unit of study after the students have already learned photosynthesis.
I also give the students two assignments based on this PPT - a PPT Worksheet and a 1-page homework worksheet. All questions on these assignments come directly from the PPT - no tricks or surprises. The Cellular Respiration PPT Worksheet is $2.50 and the Cellular Respiration Worksheet that I use as a homework assignment is FREE - both are found here in my store:)
