Answer:
D: the excess water that enters the cell allows the central vacuole to maintain turgor pressure.
Explanation:
Plant cells, which have a rigid cell wall, tend to prefer hypotonic environments. The excess water allows them to have turgor pressure. When placed in isotonic environments, plant cells do not have enough water to maintain turgor pressure and they wilt. When placed in hypertonic environments, plant cells lose too much water, causing the cell membrane to detach from the cell wall.
