The holes are there to let some things move in and out of the cell â this is called semi-permeable. The cell membrane is not one solid piece. Everything in life is made of smaller pieces and a membrane is no different. Three macromolecules combine to make cell membranes. Lipids called phospholipids make up most of the cell membrane. Proteins serve as channels, pumps or markers and make up another large portion of the cell membrane. Carbohydrates are also a part of the membrane so cells can recognize each other.
The Cell Membrane is a Fluid Mosaic. A cell is the basic unit of life, and all organisms are made up of one or many cells. One of the things that all cells have in common is a cell membrane. It is a barrier that separates a cell from its surrounding environment.he Cell Membrane is a Fluid Mosaic. A cell is the basic unit of life, and all organisms are made up of one or many cells.
