Explain the Difference Between Osmosis and Diffusion in Cells.
If a red blood cell is placed in a solution that is 12 NaCl what if anything will happen to the blood cell. Diffusion active transport osmosis. Blog Archives Science Notes Biology Classroom Interactive Notes In Osmosis the particles of solvent molecules travel across the semipermeable membrane while in diffusion the molecules from a higher to lower concentration. . Osmosis can only function in a liquid medium but diffusion can occur in all three mediums solid liquid and gas. Other solvents are not considered. Furthermore osmosis requires a semi-permeable membrane while diffusion does not. Filtration is a process of transportation of substance passively between the compartments. This is diffusioncould happen in liquids or gases. In biology this is a difference between the two processes. Osmosis is the movement of water molecules but diffusion is for any molecule. The cell membrane controls the passage of ma...
