    area of low concentration of water molecules (high concentration of dissolved particles). It is difficult to observe osmosis at the cellular level since cells are very tiny and can only be seen with a microscope‚ so you are going to use sticks of potato tissue in solutions that have different concentrations of dissolved substances to observe the effects of osmosis on living tissue. There are three basic relative concentrations of solutions. An isotonic solution has a concentration of dissolved particles
