Cell Membrane. Cell membrane or plasma membrane is a thin (5–10 nm) semipermeable membrane that acts as an osmotic barrier. It lies beneath the cell wall separating it from the cell cytoplasm. Cell membrane primarily contains phospholipids and proteins. It also contains enzymes associated with DNA biosynthesis, cell wall polymers, and

Caveolae at the plasma membrane can be removed by endocytosis to regulate their surface density or can be disassembled and their structural components

Cell membrane primarily contains phospholipids and proteins. It also contains enzymes associated with DNA biosynthesis, cell wall polymers, and 2016-08-10 · Structure of a cell membrane. Posted on August 10, 2016. On the basis of structure, cell membrane is called a unit membrane or a three-layered membrane. The electron microscopic study reveals three layers of cell membrane, namely, one central electron-lucent layer and two electron-dense layers. cell membrane structure and function 1.
