Web9 jul. 2012 · The key difference between hypotonic and hypertonic is that hypotonic solution has a low solute concentration than the cell while hypertonic solution has a high solute concentration than the cell.. … WebIsotonic solution. The prefix, iso, refers to things that are the same. It has the same concentration of solute, and so you have no net inflow. Hypotonic solution, you have water molecules going into the cell, the cell expanding, kind of like a filling balloon. Isotonic solution, no net flow.
