What are some similarities and differences between osmosis and diffusion?
-They both account for movement of molecules from a region of high concentration to a region of low concentration.
-As for osmosis;the movement of molecules are via a selectively permeable membrane. NB:only water molecules.
-Diffusion is the movement of all kinds of molecules.
They both go down a concentration gradient, but osmosis is only for solvent molecules passing through a partially permeable membrane.
Diffusion and osmosis are processes in which molecules will move from a region of a higher concentration to a region of lower concentration to establish a chemical equilibrium.
Osmosis is different than diffusion because it requires solvent molecules, like water, and only applies when passing through a selectively permeable membrane. Diffusion on the other hand, does not require a membrane to happen.
