Which definition best describes the process of diffusion?

Question

Quizplus · Accepted Answer

The process of diffusion is the movement of solute (molecules or ions) from an area of higher concentration to an area of lesser concentration, which occurs due to the random motion of particles. This movement continues until the solute becomes evenly distributed throughout the solvent. Option B is incorrect as it describes osmosis, which is the movement of water from an area of lesser concentration to an area of higher concentration. Option C is incorrect as it describes active transport, which requires energy input to transport a solute against the concentration gradient. Option D is incorrect as it describes filtration, which is the movement of solute and water caused by hydrostatic pressure differences.
