WebApr 8, 2024 · Both of these processes, diffusion and osmosis tend to equalize the concentration of the solution. Both of these processes do not require any extra energy or input hence these are called passive processes. Both of these processes observe the movement of molecules from higher concentration areas to lower concentration areas. WebMay 28, 2024 · In diffusion, particles move from an area of higher concentration to one of lower concentration until equilibrium is reached. In osmosis, a semipermeable membrane is present, so only the solvent molecules are free to move to equalize concentration. What three factors affect the concentration gradient? WebWater has a concentration gradient in this system. Therefore, water will diffuse down its concentration gradient, crossing the membrane to the side where it is less concentrated. This diffusion of water through the membrane—osmosis—will continue until the concentration gradient of water goes to zero. Osmosis proceeds constantly in living ... chuck ramsey nfl
