A
less negative because the pressure potential becomes more positive
💡 Explanation:
When a plant cell is placed in deionised water, water enters by osmosis, increasing turgor pressure. The cell wall resists expansion, creating positive pressure potential. Osmotic potential becomes slightly more negative due to dilution. The net water potential becomes less negative because the positive pressure potential increase outweighs the osmotic change. This is the classic turgor pressure development in plant cells.
