← Nature & AnimalsWhich anatomical constraint reduces photorespiration under drought conditions?
A)CAM pathway temporal partition✓
B)C4 pathway spatial separation
C)Rubisco enzyme active-site binding
D)Stomata closure timing optimization
💡 Explanation
Increased drought induces stomata closure to conserve water; the CAM pathway employs temporal partition because CO2 uptake occurs at night and photosynthesis during the day. Therefore, photorespiration decreases in CAM plants rather than alternatives relying mainly on Rubisco.
