Answer
Fluid-mosaic model of plasma membrane
Explanation
Solution
The most recent model of plasma membrane is fluidmosaic model which was proposed by Singer and Nicolson in 1972. According to this model, the membrane does not have a uniform disposition of lipids and proteins but is instead a mosaic of the two. Further, the membrane is not solid but is quasifluid.
