Cell Membrane


 * Discovery

The cell membrane was discovered by 2 swiss botanists, Carl Naegeli and C. Crame, in 1855. It was discovered 200 years after the microscope was created. The name membrane means a pliable sheetlike structure acting as a boundary. ||  Carl Naegeli  C.Crame ||
 * Functions

The functions of the cell membrane are to protect the cell and to control the movements of substances moving in and out of the cell. Phospholipid creates the basic structure of the cell membrane is called the lipid binary. Inside the lipid, binary are cholesterol molecules, scattered inside. This helps keep the membrane liquid. The smaller molecules shown in the phospholipids are Cholesterol molecules. They help to provide rigidity or stability to the membrane. The membrane proteins help to transport substances across the cell membrane. It helps with the structure of the cell because it is on the outside protected the cytoplasm on the inside of the cell. The protein channels on the inside of the cell membrane help to move in substances to the cytoplasm and into the rest of the cell. ||  This is the cell membrane structure ||

<span style="color: #666666; font-family: &#39;Bree Serif&#39;; font-size: 14pt; vertical-align: baseline;">All cells have a cell membrane but not all have a cell wall. The animal cell contains a cell membrane and a plant cell contains a cell membrane and a cell wall. All cells need a cell membrane to transport proteins into the cell. || <span style="color: #666666; font-family: &#39;Bree Serif&#39;; font-size: 18pt; vertical-align: baseline;"> <span style="color: #666666; font-family: &#39;Bree Serif&#39;; font-size: 10pt; vertical-align: baseline;">Both of the cells contain a cell membrane ||

<span style="color: #666666; font-family: &#39;Bree Serif&#39;; font-size: 14pt; vertical-align: baseline;">The cell membrane work in conjunction with the cytoplasm. It can conduct osmosis to send substances. The cell membrane can send in proteins for the cell. || <span style="color: #666666; font-family: &#39;Bree Serif&#39;; font-size: 18pt; vertical-align: baseline;"> ||
