question 2

Multiple Choice

• B) C4 compromises on water loss and CAM compromises on photorespiration.
• C) Both minimize photorespiration but expend more ATP during carbon fixation.
• D) CAM plants allow more water loss, whereas C4 plants allow less CO2 into the plant.
• E) C4 plants allow less water loss but CAM plants allow more water loss.
