Question

Quizplus · Accepted Answer

Movement of water down its concentration gradient, from an area of higher water concentration to an area of lower water concentration, is called diffusion. Osmosis specifically refers to the movement of water across a selectively permeable membrane, from an area of higher water concentration to an area of lower water concentration. Active transport requires energy and moves substances against their concentration gradient, so it is not applicable in this scenario.
