Hypotonic and hypertonic describe the concentration of dissolved substances (solutes) in a solution compared to what’s inside a cell. A hypotonic solution has fewer solutes than the cell, so water flows into the cell. A hypotonic solution has a lower concentration of solute than another solution, meaning water will flow out of it.
An isotonic solution has the same or very similar concentration of solute as another solution, meaning the water flow will reach equilibrium. Conversely, a hypotonic solution has a lower solute concentration relative to another solution or a cell’s interior. Water will move into the cell from the less concentrated external solution. An isotonic solution has the same solute concentration as another solution or the inside of a cell.
hypotonic water, A hypotonic solution has a lower solute concentration than inside the cell (the prefix hypo is Latin for under or below). The difference in concentration between the compartments causes water to enter the cell. In a hypotonic solution, water moves into plant cells, causing them to become turgid and maintain their rigidity, something that's absolutely essential for the health and growth of the plant. A solution is considered hypotonic if it contains a lower solute concentration or higher water content than another solution. The Greek word ‘ hypo ’ stands for ‘under’ or ‘low’, whereas ‘tonic’ is derived from ‘tonicity’, which means ‘relative concentration of a solution’.
hypotonic water, The term hypotonic has two parts: hypo means “less/under/beneath,” and tonic means “stretching or concentration of a solution.” A solution with a lower solute concentration or lower osmotic pressure across a semipermeable membrane is called a hypotonic solution. If the solute concentration outside the cell is lower than inside the cell, and the solutes cannot cross the membrane, then that solution is hypotonic to the cell.
