For C3 plants during the day, a CO2 gradient is maintained between the inside and outside of a leaf because: a. Energy is expended by the plant to maintain the CO2 gradient. b. The stomata close whenever more CO2 is needed. c. The CO2 concentration outside the leaf is always increasing. d. The CO2 concentration in mesophyll cells is constantly decreasing.

Step 1
Energy is expended by the plant to maintain the CO2 gradient: This is true, as the plant uses energy to open and close stomata and to fix CO2 during photosynthesis. However, let's check the other options before deciding. b. The stomata close whenever more CO2 is Show more…

During C4 photosynthesis: a) plants use less ATP when producing sugar. b) plants are able to continue producing sugars even when they must close their stomata to reduce water loss on hot days. c) plants are able to generate water molecules to cool their leaves. d) plants are able to reduce water loss by producing more rubisco. e) plants are able to produce sugars without any input of carbon dioxide.
