    D Water potential gradient Correct Answer Incorrect Answer
    E Root pressure Correct Answer Incorrect Answer

    Solution

    Water moves from regions of higher water potential (soil) to lower water potential (atmosphere) through the plant. This gradient, driven by transpiration, ensures continuous water flow.
