Question

    In the soil water-plant continuum, what is the driving

    force that allows water to move from the soil through the plant to the atmosphere?
    A Capillary movement Correct Answer Incorrect Answer
    B Osmotic pressure Correct Answer Incorrect Answer
    C Pressure gradient Correct Answer Incorrect Answer
    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.
