... early prokaryotic cell was engulfed by another prokaryotic cell, and that there singular membranes worked together, and formed a double membrane which is more efficient, this is called endosymbiosis. The idea of this fluid mosaic model is to stop the cell from diffusing into its surroundings, if this happens the genetic make up of the cell would be lost, and the metabolic pathways would seek a thermal equilibrium, thus destroying the cell. Therefore to have a fluid mosaic model which can control what diffuses/osmosis's into and out of the cell is a feature that is extremely beneficial to the cell. [1] [2] Each component within the fluid mosaic model serves a task that is important to the function and structure of the membrane. For example, the integral proteins serve a structural and functional task, it can also penetrate both sides of the lipid bilayer, Integral membrane proteins are embedded in the ...
