How does osmosis diffusion play a role in the movement of substances across a semipermeable membrane?

Osmosis and diffusion are processes that allow substances to move across a semipermeable membrane. Osmosis is the movement of water molecules from an area of low solute concentration to an area of high solute concentration, while diffusion is the movement of solute molecules from an area of high concentration to an area of low concentration. Together, osmosis and diffusion help maintain balance and regulate the movement of substances across the membrane.
