5 / 5 pts (short answer) What is the fluid mosaic model and what feature of the cells does it help us understand? The fluid mosaic model helps us understand biological membranes. It describes the fluid, complex nature of the membrane bilayer. Membranes have lipids and proteins in a rich mixture to help the cell survive.
