Explanation
Hugh Davson and James Danielli proposed the Davson–Danielli model in 1935.
It described cell membranes as consisting of a phospholipid bilayer sandwiched between two layers of globular proteins.
This model was also known as the paucimolecular model.
In 1972, S. Singer and G. Nicolson proposed the fluid mosaic model.
It described cell membranes as consisting of a phospholipid bilayer with embedded proteins, cholesterol, and carbohydrates.
This model has been proven to be true.
