Plasma membrane is a border that covers all cells. This coating is difficult, due to the parts always moving allowing specific materials into the cell and keeping substances away. Phospholipid bilayer is what plasma membrane is made of, and they are membrane proteins. “Because it is made of different pieces that form a pattern and seem to float and move in watery environments” (Daempfle, 2016) the plasma membrane is called the fluid mosaic. The fluid mosaic model consists of several macromolecules. Integral proteins spread the whole lipid bilayer; peripheral proteins which sits either inside or outside of the membrane. These two macromolecules serve as foundation cells to one another to transport materials across the membrane, take in chemicals,
