Question

which best describes the difference between osmosis and diffusion?
osmosis is the movement of particles from a high to a low particle concentration, while diffusion is the movement of water from a high to a low water concentration.
diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
diffusion is the movement of particles from a low to a high particle concentration, while osmosis is the movement of water from a low to a high water concentration.
osmosis is the movement of particles from a low to a high particle concentration, while diffusion is the movement of water from a low to a high water concentration.

Explanation:

Diffusion is the passive movement of particles (solute or gas etc.) from an area of high - particle concentration to an area of low - particle concentration. Osmosis is the passive movement of water molecules across a semi - permeable membrane from an area of high water concentration (low solute concentration) to an area of low water concentration (high solute concentration).

Answer:

B. Diffusion is the movement of particles from a high to low particle concentration, while osmosis is the movement of water from a high to a low water concentration.
