Answer:
Osmosis
Explanation:
In osmosis, the direction of water flow is determined by solute concentration. Water diffuses from a hypotonic (low solute concentration) solution to a hypertonic (high solute concentration) solution. In the example above, water moves from the left side of the semi-permeable membrane, where the sugar concentration is low, to the right side of the membrane, where the sugar molecule concentration is higher. If the molecule concentration were the same on both sides of the membrane, water would flow equally (isotonic) between both sides of the membrane.
