A cell membrane is a thin layer that acts as a barrier that separates an individual cell or a cellular compartment from other surrounding structures. This dynamic layer plays an es...
The cell membrane (or plasma membrane or plasmalemma) surrounds the
cytoplasm of living cells, physically separating the intracellular components from
Cell membrane is like a plastic bag According to cell theory, cells are the main
unit of organization in biology. Whether you are a single cell or a blue whale with
The cell membrane
is primarily composed of a mix of proteins and lipids . They form a lipid bilayer in which their hydrophillic (attracted to water) head areas spontaneously arrange to face the aqueous cytosol and the extracellular fluid, while their hydrophobic (repel... More »
There are many different kinds of membranes in a cell. Learn how they subdivide
sections of a cell and how proteins in these membranes are gatekeepers for ...
The structure and function of cells are critically dependent on membranes, which
not only separate the interior of the cell from its environment but also define the ...
The Cell Membrane. All living cells and many of the tiny organelles internal to
cells are bounded by thin membranes. These membranes are composed
Learn about how phospholipids form the cell membrane, and what types of
molecules can passively diffuse thorugh the membrane. By William Tsai.
Cell Membranes. One universal feature of all cells is an outer limiting membrane
called the plasma membrane. In addition, all eukaryotic cells contain elaborate ...
