Introduction: human blood, at 09% salt concentration, is a little less salty than seawater, which has a salt concentration of about 35 parts per thousand (35%) if we take seawater as an example of a solution, the salt is called the solute (the particles that are dissolved) and the water is the solvent (the liquid that dissolves the. Osmosis & diffusion lab – dialysis tubing background the movement of molecules through a cell membrane is termed osmosis or diffusion such movement is principally possible because nutritive molecules are smaller than membrane micro pores if the molecules are too large, no molecular transfer, or diffusion occurs.
