Osmosis Driven by Water Potential Differences Steps: - 1. Recall that water moves across semi-permeable membranes from higher to lower water potential via osmosis. - 2. For a plant cell, volume increases if the solution's water potential (ψ) exceeds the cell's ψ, as water enters. - 3. Volume remains unchanged if solution ψ equals cell ψ, with no net water movement. - 4. Given the solutions' different ψ values, the first and third cause water influx (ψ > cell ψ), while the second matches (ψ = cell ψ), yielding increased, no change, increased volumes. Why B is correct: - B aligns with osmosis, where water enters cells in solutions with higher ψ (first and third) and shows no net change when ψ is equal (second). Why the others are wrong: - A: Wrongly predicts decreases for first and third, implying ψ < cell ψ, contradicting the given ψ conditions. - C: Incorrectly shows decrease for first, which requires ψ < cell ψ, not matching the scenario. - D: Duplicate of B, but as a distinct option, it fails to uniquely …
