Which outcome occurs when increased atmospheric back-pressure impacts plant transpiration?

💡 Explanation

The xylem sap ascent rate reduces because an increase in atmospheric back-pressure decreases the water potential gradient between the leaves and the atmosphere, limiting transpiration. Therefore, the transpiration-driven water movement diminishes, rather than stomatal function being directly impacted, due to external limitations.
