Osmosis diffusion

The fundamental difference between the two is – osmosis is the movement of the solvent (water) from a region of higher concentrations to the. Osmosis and diffusion are two processes that involve the transmission of particles from one area to another osmosis is actually a specific type of diffusion. There are two passive processes which can occur in cells: diffusion and osmosis • substances may pass through the cell membrane actively by active transport. Diffusion, osmosis, active transport there are two ways in which substances can enter or leave a cell: 1) passive a) simple diffusion b) facilitated diffusion.
