Question

Quizplus · Accepted Answer

Osmosis is the diffusion of water from a region of higher water concentration to a region of lower water concentration, across a semi-permeable membrane. Therefore, both the presence of a semi-permeable membrane and the diffusion of water are essential components of osmosis. Transport proteins are not directly involved in osmosis.
