  Which modern theory describes the structure of cell membrane?

A.   *Fluid mosaic model

B.   Bilaminar model

C.    Multilayered model

D.   Complex model

Functional model 

Fluid Mosaic model

according to fluid mosaic model "biological membranes can be considered as a two-dimensional liquid in which lipid and protein molecules diffuse more or less easily. Although the lipid bilayers that form the basis of the membranes do indeed form two-dimensional liquids by themselves, the plasma membrane also contains a large quantity of proteins, which provide more structure."
