Ans 18 :
According to the fluid mosaic model of membrane , the membrane is a mosaic of different components that make up the structure of the membrane.
These components are : phospholipids , proteins , carbohydrates , cholesterol etc.
So the model states that the membrane is made up of a bilayer of phospholipids . This layer of amphipathic molecules have molecule of protein embedded in them.
The layer of these lipid molecules is flexible i.e. fluid and the protein molecules act as a channel that help allow the transfer of molecules across the membrane.
