← Nature & AnimalsWhich outcome results when alpine plants employ the CAM pathway?
A)Stomata close during daylight hours
B)Increased photorespiration rate results
C)Water loss decreases significantly overnight✓
D)Carbon fixation occurs only in mesophyll
💡 Explanation
The CAM pathway evolved to conserve water, because stomata open to fix CO₂ nocturnally, therefore reducing daytime water loss rather than increasing photorespiration, because this is an adaptation for arid environments.
