← Nature & AnimalsWhich risk increases when stomata close due to salinity?
A)Reduced xylem water column diameter
B)Decreased osmotic potential gradient
C)Interrupted transpiration pull mechanism✓
D)Accelerated nutrient transport in phloem
💡 Explanation
Interrupted transpiration in leaves creates cavitation; because reduced water cohesion impairs the transpiration pull mechanism, water & nutrient supply decreases. Therefore, this happens rather than pholem increasing, gradients changing and xylem varying directly.
