Answer:
Before we look at the difference between Endosmosis And Exosmosis, let’s brush up the basics of what exactly is “osmosis.” Osmosis is the movement of a solvent (such as water) from a low solute concentration into a solution that has a higher solute concentration through a semipermeable membrane. The flow of this solution stops when equalization happens on both sides of the membrane.
Osmosis is of two types- endosmosis and exosmosis
Endosmosis
When a cell is placed in a hypotonic solution, the water moves inside a cell and swells. This movement of water inside a cell is known as endosmosis. This happens because the solute concentration of the surrounding solution is less than that inside the cytoplasm.
Exosmosis
When a cell is placed in a hypertonic solution, the water moves out of the cell and the cell becomes flaccid. This movement of water out of the cell is known as exosmosis. This happens because the solute concentration of the surrounding solution is higher than that inside the cytoplasm.
