← Nature & AnimalsWhich risk increases when prolonged drought induces root cavitation?
A)Increased chlorophyll synthesis efficiency
B)Reduced transpiration rate stability✓
C)Uncontrolled stomatal aperture dilation
D)Enhanced nutrient uptake efficiency
💡 Explanation
Reduced transpiration rate stability occurs upon root cavitation during drought when water columns break, therefore disrupting the cohesion-tension mechanism. This impedes continuous water transport, rather than optimizing nutrient uptake, because cavitation diminishes water's cohesive properties.
