Lab 1: Diffusion & Osmosis

Lab 1: Diffusion & Osmosis Description dialysis tubing filled with starch-glucose solution in beaker filled with KI solution potato cores in sucrose solutions

Lab 1: Diffusion & Osmosis Concepts semi-permeable membrane diffusion osmosis solutions hypotonic hypertonic isotonic water potential

Lab 1: Diffusion & Osmosis Conclusions water moves from high concentration of water (hypotonic=low solute) to low concentration of water (hypertonic=high solute) solute concentration & size of molecule affect movement through semi-permeable membrane
