The concentration of dissolved substances in cell sap is usually higher than in the fluid surrounding the cell.
What effect does this have on water movement into the vacuole?
Correct Answer
Water moves into the vacuole by osmosis, keeping the cell turgid
Explanation
Because cell sap is hyperosmotic (higher solute concentration) relative to the external medium, water moves into the vacuole by osmosis. This influx of water creates turgor pressure, which keeps the cell firm (turgid) and helps support the plant's structure.
