← Nature & AnimalsWhich limitation is bypassed when CAM plants use temporal separation of photosynthetic pathways?
A)Excessive water loss in arid environments✓
B)Nitrogen depletion from rapid growth
C)Chlorophyll degradation from high radiation
D)Inability to fix carbon at low temperatures
💡 Explanation
When CAM plants fix CO2 at night and perform the Calvin cycle during the day, they bypass the limitation of excessive water loss in arid environments because stomata are open when temperatures are cooler and humidity is higher at night. Therefore, reduced water loss results, rather than other issues which correlate with separate environmental stressors.
