CAM and C4 plants conduct photosynthesis in ways that allow them to live in drier areas than most C3 plants can tolerate. The effectiveness of different plants in restricting water loss while still allowing for influx of adequate carbon dioxide can be compared using the transpiration ratio, which is calculated by dividing the amount of water transpired by the amount of carbon dioxide fixed by photosynthesis. If a typical transpiration ratio for a C3 plant is 500, then possible values for CAM and C4 plants could be ________.

Question

Quizplus · Accepted Answer

CAM 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.
