... process of diffusion of water is a passive process, meaning without any use of energy. Diffusion is imperative for the distribution of ion and other solutes within a cell. Small molecules and ions may move from one end of an organelle to another in a fraction of a millisecond, or from the center of a cell to its surface almost as fast. There are two types ... of diffusion across the membrane barrier: OSMOSIS: It depends on concentration of solutes in an aqueous solution on the two sides seperated by a membrane. Solute concentration is related to osmotic pressure. Greater the solute conc...

... the cell, water will pass into the cell through the process above. If the cell surroundings have a greater concentration, then water disperses from the cell. When unequal solute concentrations in aqueous solutions are on either side of semi permeable membrane, water always moves from the hypotonic solution (lower solute concentration and higher water molecule concentration), to the hypertonic solution (higher solute ... carried through membrane associated pumps. Special transport macromolecules that exist in the cell membrane move molecules across the membrane. Among the molecules that ...
