CAM and C₄plants conduct photosynthesis in ways that allow them to live in drier areas than most C₃plants can tolerate. The effectiveness of different plants in restricting water loss while still allowing for influx of adequate CO₂can be compared using the transpiration ratio, which is calculated by dividing the amount of water transpired by the amount of CO₂fixed by photosynthesis. If a typical transpiration ratio for a C₃plant is 500, then possible values for CAM and C₄plants could be

Question

Quizplus · Accepted Answer

CAM (Crassulacean Acid Metabolism) and C4 plants have adaptations that allow them to photosynthesize more efficiently in dry environments, typically resulting in lower transpiration ratios compared to C3 plants. This means they lose less water per unit of CO2 fixed, so their transpiration ratios would be lower than that of a typical C3 plant, which is given as 500.
