How to use osmosis in a sentence movement of a solvent (such as water) through a semipermeable membrane (as of a living cell) (see diffusion 3a). When a plant cell is immersed in a solution with lower water potential, the water potential of its cell sap is higher than that of the solution outside the cell. 1 third misconceptions seminar proceedings (1993) paper title: freshman biology non-majors misconceptions about diffusion and osmosis. Molecules are always on the move thanks to kinetic energy this energy makes diffusion and osmosis possible, two processes used by cells to. Abstract osmosis through semi–permeable pores is a complex process by which solvent is driven by its free energy gradient towards a solute–rich reservoir.
