isotonic solutions have the same concentration of osmotically active particles (osmotically active particles are non-permeable particles) as are found in the cell.

  • What is hypotonic?
  • What is tonicity?
  • What is isotonic?
  • What is isosmotic?
if the cell shrinks (crenates) we say the solution was hypertonic.

  • What is hypertonic?
  • What is hyperosmotic?
  • What is hyposmotic?
  • What is hypotonic?
Osmolarity doesn't take into account the nature of the solutes while tonicity is dependent upon the concentration of the nonpermeable solutes.
  • Why do we need a selectively permeable membrane for osmosis to occur?
  • What is isotonic?
  • What is the difference between osmolarity and tonicity?
  • What is osmotic pressure?
For osmosis to occur the membrane must be permeable to water but impermeable to the solute and the concentration of the solute must be different on the two sides of the membrane.

If the cell swells, we say that the solution was hypotonic.

  • What is hyposmotic?
  • What is hypotonic?
  • What is hyperosmotic?
  • What is hypertonic?
By definition, osmosis is the diffusion of water through a selectively permeable membrane from an area of high water potential (low solute concentration) to and area of low water potential (high solute concentration).

This means that one solution is less concentrated than the other.
