osmosis is the diffusion of water molecules across a partially permeable membrane from an area of higher water potential to an area of lowerwaterpotential
water potential is the potential of water molecules to diffuse out of a solution
pure water has the highest water potential
if two solutions have the same water potential, they're isotonic
the moresolute in a solution, the lower the water potential. the lower concentration of water molecules, the lower the water potential
