Why is the model of the cell membrane referred to as fluid mosaic?

Who proposed fluid mosaic model?

The fluid mosaic hypothesis was formulated by Singer and Nicolson in the early 1970s [1]. According to this model, membranes are made up of lipids, proteins and carbohydrates (Figure 1).

What happens to membrane permeability below 0?

Generally, increasing the temperature increases membrane permeability. At temperatures below 0 oC the phospholipids in the membrane don’t have much energy and so they can’t move much, which means that they’re closely packed together and the membrane is rigid.

Why do both surfaces of your membrane model need to be hydrophilic?

The interior and the exterior of cells is liquid, usually a solution or suspension of ions, small molecules and large molecules dissolved in water. Proteins must therefore be hydrophilic (“water loving”) in order to be suspended in this environment.
