Structure of Plasma Membrane: The plasma membrane is approximately 7.5 nm (0.0075 µm) thick, forms the limiting boundary of the cell and is made up of phospholipids (about 20-30%) and proteins (about 60-70%).
WebSolution Verified by Toppr The fluid mosaic model of the plasma membrane was given by Singer and Nicolson in 1972. According to this model, the plasma membrane is made of a phospholipid bilayer with cholesterol, protein, and carbohydrate molecules embedded in it. This membrane is 5-10nm in thickness. WebThis structure maintains the cell’s shape, protects the cell interior, and prevents the cell from bursting when it takes up water. ... Underneath the cell wall lies the plasma membrane. The basic building block of the plasma membrane is the phospholipid, a lipid composed of a glycerol molecule attached a hydrophilic ...
WebAlthough it's not technically inside the cell, the plasma membrane is also part of the endomembrane system. As we'll see, the plasma membrane interacts with the other endomembrane organelles, and it's the site where secreted proteins (like the pancreatic enzymes in the intro) are exported.
