← Nature & AnimalsWhich process reduces a leafy plant's transpiration rate under extremely high atmospheric pressure?
A)Stomatal closure mechanism✓
B)Increased root pressure activity
C)Decreased embolism formation
D)Accelerated water transport velocity
💡 Explanation
Very high atmospheric pressure forces stomata closed via turgor regulation, reducing transpiration because the stomatal closure mechanism prevents effective gas exchange. Therefore, less water vapor escapes rather than pressure forcing more open causing accelerated gas exchange.
