- The cell membrane controls what enters and leaves the cell, allowing the cell to absorb the oxygen and nutrients it needs to function and also protects the cell from most dangerous chemicals. It is vital because the cell needs to be able to control its oxygen and carbon dioxide levels. cell membrane protects a cell by controlling what substances go in and out of the cell. It lets good products go inside, but harmful products go out, which is basically prot … ecting the cell.

Functions of the Cell Membrane Both eukaryotic cells, including plant cells and animal cells, and prokaryotic cells, e.g. bacteria, are enclosed by a cell membrane. A cell membrane (see the simple diagram on the right) is a thin structure that is also known as the plasma membrane. The main functions of the cell membrane are:

Cell Membrane Function and Structure It also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape. Another function of the membrane is to regulate cell growth through the balance of endocytosis and exocytosis.

An In-depth Look at the Structure and Functions of the Cell Membrane There are certain proteins that are responsible for transportation of ions and molecules across the cell membrane. Some of these proteins have other functions, like cell to cell communication, identification, enzymatic activities and signaling. The main components of the cell membrane are phospholipids and proteins. However, it has cholesterol molecules that make the membrane rigid and flexible. They also make it difficult for water soluble substances to pass through the membrane.

Cell Membrane Function and Structure Cell membrane proteins have a number of different functions. Structural proteins help to give the cell support and shape. Cell membrane receptor proteins help cells communicate with their external environment through the use of hormones, neurotransmitters, and other signaling molecules. Transport proteins, such as globular proteins, transport molecules across cell membranes through facilitated diffusion.

What Are the Benefits of Fruits & Vegetables for Kids? Digestive Health. High-fiber foods, such as fruits and vegetables, help the digestive system function properly. Constipation in kids can often be eased by eating more high-fiber prunes, apricots, plums, peas, beans and broccoli, according to the American Academy of Pediatrics. As fiber passes through the digestive system, it absorbs water and expands, which triggers regular bowel movements and relieves constipation.
