Diffusion and Osmosis - Difference and Comparison

WebThe primary differentiating factor between the two systems is the medium in which they are employed. Osmosis can only function in a liquid medium, but diffusion can occur in all three mediums (solid, liquid and gas). Furthermore, osmosis requires a semi-permeable membrane, while diffusion does not. The intake of water in plants is an example of ... WebApr 26, 2024 · Osmosis and diffusion play essential, but distinct roles in life. Diffusion sees molecules in an area of high concentration move to areas with a lower concentration, while osmosis refers to the process by which …
