← Nature & AnimalsWhich outcome occurs when prolonged flooding occludes plant stomata?
A)Accelerated anaerobic root respiration
B)Enhanced foliar heat dissipation
C)Increased nutrient uptake efficiency
D)Reduced transpiration-driven water transport✓
💡 Explanation
When stomata are blocked by flooding, transpiration decreases because gaseous exchange diminishes, leading to lessened water transport from roots to leaves driven by transpiration pull. Therefore water transport reduction results, rather than anaerobic respiration, heat dissipation, or increased uptake, which depend on open stomata and aerobic root function.
