This activity has been entirely revised to help students develop a sophisticated understanding of the basics processes of photosynthesis and cellular respiration. New sections develop student understanding that the (1) products of photosynthesis are used not only for cellular respiration, but also to synthesize plant molecules and (2) photosynthesis can increase plant biomass and cellular respiration can decrease plant biomass, so changes in a plant’s biomass depends on the balance between photosynthesis and cellular respiration. An answer key is now available for this activity.
