What happens to the tension in the xylem when the stomata close and evaporation stops?

Question

Quizplus · Accepted Answer

When stomata close and evaporation stops, the tension in the xylem drops due to a decrease in water movement through the stomata, leading to reduced transpiration. As a result, the water potential gradient between the leaf and the soil decreases, and the tension in the xylem drops to a value closer to that of the water-filled pores in the soil. However, the tension does not go to zero as the roots still need to uptake water from the soil.
