Question 8 • CMS 2026-2027 Biology CREDIT RECOVERY

Which best describes the difference between osmosis and diffusion?

Answer

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.

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.

Explanation

Diffusion is the movement of particles from an area of higher particle concentration to an area of lower particle concentration. Osmosis is the movement of water across a selectively permeable membrane toward an area of lower water concentration. Therefore, choice C correctly describes both processes.
