Which statement best describes osmosis?
A)active transport of water across the cell membrane
B)diffusion of water from a greater to a lesser water concentration
C)movement of water into a solute
D)diffusion of water from a greater to a lesser water concentration across a selectively permeable membrane
E)random movement of water due to kinetic energy

Question

Quizplus · Accepted Answer

Osmosis is the passive diffusion of water molecules from a region of higher water concentration to a region of lower water concentration across a selectively permeable membrane. It does not require energy input from the cell. Therefore, option D, which states diffusion of water from a greater to a lesser water concentration across a selectively permeable membrane, best describes osmosis.
