Hypotonic, isotonic, and hypertonic solutions (tonicity) In an isotonic environment, there is the same amount of water on each side, so there is no change in the size of the cell When a cell is placed in a hypotonic environment, water will enter the cell, and the cell will swell You can use prefixes to help you
Khan Academy If a cell is placed in an isotonic solution, there will be no net flow of water into or out of the cell, and the cell’s volume will remain stable A solution is considered isotonic if its solute concentration is the same as the solute concentration inside the cell
Khan Academy In an isotonic solution, there is no net flow of water, keeping the cell stable In a hypertonic solution, water leaves the cell, causing it to shrivel These reactions are due to the semipermeable nature of cell membranes and the concentration of solutes Created by Sal Khan
Osmosis and tonicity review (article) | Khan Academy Hypertonic and hypotonic are not the same If a cell is put into a hypertonic solution, water will leave the cell A quick tip to remembering this is to visualize “hyper” kids who want to go play outside! In contrast, when a cell is put into a hypotonic solution, water will enter the cell Another trick to remembering this is that the cell swells and gets round like the “o” in hypo!
