In membranes phospholipids associate to form two layers.
Larger proteins float within the bilayer.
Integral membrane proteins can move laterally in a membrane.
Explanation:
The fluid mosaic model is a model in which the structures of cell membranes are established. The flexible layer is made up of lipids, which are interspersed with a large protein. Other molecules can enter or leave through these channels.
The Fluid Mosaic Model declares that membranes are formed of a Phospholipid Bilayer with several protein molecules drifting about inside it. The ‘Fluid’ section describes how any components of the membrane can run nearby loosely if they are not connected to different components of the cell. The ‘mosaic’ section explains the ‘patchwork’ of proteins that are detected in the Phospholipid Bilayer.
<h3>Explanation:</h3>
There is a lipid bilayer in which the protein molecules are embedded. The lipid bilayer gives fluidity and elasticity to the membrane. Carbohydrates are also found in a cell membrane. The plasma membrane is said to be two-dimensional structure or liquid we can say which does not allow the lateral diffusion of membrane components. The plasma membrane has the texture of vegetable oil at body temperature, because of which the proteins and other substances move across it. That's why the plasma membrane is described as using the fluid-mosaic model.
Emigration means an animal leaves its home because the habitat is no longer ideal for them, and they need to find a more suitable environment. Animals that immigrate or emigrate do not return to the land they left.
