The phospholipid bilayer, also known as the cell membrane.
The cell membrane.
A plasma membrane is described as mosaic because all the different components such as proteins and phospholipids, of varying shape and size, give the effect of the stones of a mosaic. It is described as fluid because these components can move freely within the membrane.
embedded in a lipid bilayer
False; the fluid mosaic model describes the plasma membrane as a flexible boundary of a cell.
The lipids molecules that form the membrane are fluid. They can move about relative to one another in a fluid manner. Some of the proteins are also free to move about so that the mosaic or pattern of lipids and proteins changes. Because of these characteristics scientists call their model of the dynamic cell membrane the fluid the fluid mosaic model.

False; the fluid mosaic model describes the plasma membrane as a flexible boundary of a cell.
The fluid mosaic model serves to describe the cell membrane and how it functions. The 'fluid' describes its nature, rather than being solid, and the 'mosaic' describes its many and different parts, such as proteins, phospholipids, and in some cases cholesterol.
The fluid mosaic model, of corse!

cell membrane
fluid: as the phospholipid bilayer can move sideways freely within the plasma membrane mosaic: the pattern formed by the intrinsic and extrinsic proteins within the plasma membrane ** The molecules are like the tiles of a mosaic but rahter then being embedded in a solid cement-like material, they are embedded in a fluid and can move slightly to allow the passage of materials across the cell membrane and thus into the sytoplasm of the cell.
Fluid refers for the frequent lateral movement of phospholipids within the membrane. Mosaic refers to the collage of intrinsic proteins that stud the membrane.
