Quizplus · Accepted Answer

The Fluid Mosaic Model describes the cell membrane as a two-dimensional liquid of mixed composition, meaning that it contains lipid, protein, and carbohydrate components that are able to move within the plane of the membrane. The other answer choices (Diffusion, Hypertonic, Isotonic, Osmosis) are related to different concepts of membrane transport and do not describe the physical nature of the membrane itself.
