Answer:

Different between osmosis and diffusion

Osmosis only allows solvent molecules to move freely, but diffusion allows both solvent and solute molecules to move freely. ... Osmosis happens when molecules move from higher to lower concentrations, but diffusion happens when it is reversed.

how does a cell membrane control these two process

Passive osmosis and diffusion

Passive osmosis and diffusionBecause the membrane acts as a barrier for certain molecules and ions, they can occur in different concentrations on the two sides of the membrane. Such a concentration gradient across a semipermeable membrane sets up an osmotic flow for the water.
