A)the movement of solute molecules from a higher concentration to a lower concentration.
B)diffusion of water across a selectively permeable membrane.
C)likelihood that water will diffuse in a particular direction.
D)lower concentration of a solute in a solution.
E)movement of water toward a higher water concentration.

Question

Quizplus · Accepted Answer

Osmosis is defined as the diffusion of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration, in order to achieve equilibrium. Option B accurately describes this process. Option A describes diffusion, but not specifically osmosis. Option C describes the probability of diffusion occurring, but not the process of osmosis itself. Option D describes the concentration of solute in a solution, which is related to but not the same as osmosis. Option E describes the opposite process of osmosis, which would be facilitated diffusion.
