the difference between osmosis and simple diffusion is that
only simple diffusion refers to the movement of molecules across a semipermeable membrane.
osmosis refers specifically to the movement of water, whereas simple diffusion refers to the movement of a variety of molecules.
only in simple diffusion do molecules move from areas of high concentration to areas of low concentration.
simple diffusion is passive transport, whereas osmosis is active transport.

Explanation:

Osmosis is a specialized type of passive diffusion that only involves the movement of water across a semipermeable membrane from high to low water concentration. Simple diffusion is the passive movement of any small, non-polar molecule down their concentration gradient across a membrane. Both are passive, move down concentration gradients, and cross semipermeable membranes, so only the option distinguishing their target molecules is correct.

Answer:

osmosis refers specifically to the movement of water, whereas simple diffusion refers to the movement of a variety of molecules.
