In order for us to appreciate these special adaptation‚ we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. In this lab‚ we will determine the effects of hypertonic‚ isotonic and hypotonic solutions on plant and animal cells. In general when an animals cell’s placed in hypertonic solution it shrivels; a plant cell on the other hand undergoes plasmolysis. When an animal
