Lab: Diffusion Across a Semi-permeable Membrane — Unit test

Question 17 • HVA 26-27 IM Biology A

Which best describes the difference between osmosis and diffusion?

Answer

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 net 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, from higher water concentration to lower water concentration. Choice B correctly distinguishes the two processes.
