Question

    How do plants establish a pressure gradient to facilitate water movement in the soil?

    A By increasing the hydraulic conductivity of the soil Correct Answer Incorrect Answer
    B By reducing soil porosity Correct Answer Incorrect Answer
    C By depleting the soil of water near the root surface Correct Answer Incorrect Answer
    D By reducing transpiration rates Correct Answer Incorrect Answer

    Solution

    As plants absorb water from the soil, water is depleted near the root surface, creating a pressure gradient with respect to neighboring regions of soil that have higher pressure.
