Back

The diffusion of water across a selectively permeable membrane.

Front

What is the difference between active and passive transport?

Back

Active transport requires energy, while passive transport does not.

Front

What happens during equilibrium in diffusion?

Back

Particles are evenly distributed and there is no net movement.
