Quizplus · Accepted Answer

Cellular membranes are constantly in motion and have a fluid nature, allowing for the movement of molecules and proteins within the membrane. This was first proposed by the fluid mosaic model of the cell membrane. Rigid and symmetrical membranes would limit the movement of molecules and proteins. Cellular membranes are selectively permeable and allow small molecules and ions to pass through but are less permeable to large molecules. Membranes are composed of both polar and nonpolar regions.
