Rate this question:
Nothing major. Cells are hypertonic too, so water will continue to move in and out through the membrane at equilibrium.
The cell is likely to swell and may even burst as water moves from the solution into the cell.
The cell is likely to shrivel up as water leaves the cell and flows into the hypertonic solution.
The cell is likely to alternate between swelling and shriveling as water moves in and out.
None of the above. Transport of water across the membrane is controlled by the cell.
