The term 'diffused through a membrane' can be summarized by the word 'osmosed, ' which is a seven-letter word. Osmosis is a process in which molecules of a solvent, such as water, pass through a semipermeable membrane from a region of higher concentration to a region of lower concentration. This process is driven by the natural tendency of the solvent to equalize its concentration on both sides of the membrane. In other words, osmosis is the diffusion of a solvent through a semipermeable membrane.
