WebOsmosis is the movement of water across a semipermeable membrane in the direction of a more hypertonic environment. Osmosis can be thought of as a "sucking pressure" that draws water in its direction. Osmosis plays a role in maintaining a constant environment in the cells of the body. WebHypotonic solution. Hypertonic solution. Solution is hypotonic to the cell if the solute concentration outside the cell is lower compared to inside the cell. Solution is hypertonic to the cell if the concentration of solutes is higher compared to inside the cell. As a result of flow of water into cell, the cell gains volume and swells.
