Answer: The water will flow equally in both environments in and out of the cell.
Explanation:
Osmosis can be defined as the process in which the water or any other fluid moves from a higher concentration to lower concentration across a semi-permeable membrane.
In an isotonic solution the concentration of the solvent is same in both the environments that is inside and outside the cell. So the water or any other solvent will move or flow in defined equal volumes in each solution and the other solution.
