The Cell Membrane Cellsare the basic building block of all living things. Someliving things are composed ofonly a single cell, while others are composed of many cells. What cells do depends on their location in an organism. Cells can work together to serve a particular function in the form...
The cell membrane – also called the plasma membrane or cytoplasmic membrane – is among the most fascinating and elegant constructs in the world of biology. The cell is considered the fundamental unit or "building block" of all living things on Earth; your own body has trillions of them, an...
In plants, the cell membrane is located between the cell cytoplasm and the cell wall. As is the case with animal cells, the cell membrane in plants is a lipid bilayer. It's made up of phospholipids and also contains protein and carbohydrate molecules. Here, the cell membrane is involved i...

Therefore, the collection of lipids and proteins that make up a cellular membrane relies on natural biophysical properties to form and function. In living cells, however, many proteins are not free to move. They are often anchored in place within the membrane by tethers to proteins outside the...

Despite differences in structure and function, all living cells in multicellular organisms have a surrounding cell membrane. As the outer layer of your skin separates your body from its environment, the cell membrane (also known as the plasma membrane) separates the inner contents of a cell from...
The cell membrane is a barrier that controls the exchange of compounds and information between the outer and inner parts of the cell. In order to achieve this function, cell membranes contain embedded membrane proteins that play different roles. Several of families of membrane proteins have been ...
The cell membrane (plasma membrane) is a thin semi-permeable membrane that surrounds thecytoplasmof acell. Its function is to protect the integrity of the interior of the cell by allowing certain substances into the cell while keeping other substances out. It also serves as a base of attachmen...
