← Nature & AnimalsWhich outcome results when desert succulents utilize CAM pathways during prolonged drought?
A)Reduced water loss via stomatal closure✓
B)Increased photosynthetic activity at night
C)Enhanced carbon fixation in mesophyll cells
D)Elevated transpiration rates in the sunlight
💡 Explanation
During prolonged drought, desert succulents use CAM because stomata open at night for CO2 uptake and close during the day in response to avoid water loss via transpiration, improving water use efficiency. Therefore, the reduced water loss occurs, rather than increased photosynthesis or carbon fixation, which would require open stomata during the day.
