Key points to Remember about Osmosis 

  1. Osmosis is a process by which Substances are passed through a semipermeable membrane from a lower concentration to a high concentration.
  2. There are two types of osmosis: 
  3. Endosmosis: The process in which a substance is placed in a hypotonic solution, in which the solvent molecules move inside of the cell and the cell becomes turgid or undergoes deplasmolysis. This is called endosmosis.
  4. Exosmosis: This is a process in which a substance is placed in a hypertonic solution, the solvent molecules move outside the cell and the cell becomes flaccid or undergoes plasmolysis. This is called exosmosis.
  5. There are three different types of solutions for osmosis: Hypotonic, isotonic and hypertonic solution.
  6. A hypotonic solution contains a high amount of solute concentration inside the cell than outside.
  7. An isotonic solution that contains the same concentration of solutes both inside and outside of the cell.
  8. A hypertonic solution contains a higher solute concentration outside of the cell than inside.
