According to fluid mosaic model, plasma membrane is composed of (a) phospholipids and oligosaccharides (b) phospholipids and hemicellulose (c) phospholipids and integral proteins (d) phospholipids, extrinsic proteins and intrinsic proteins.
Option C According to the fluid mosaic model of cell membrane structure proposed by Singer and Nicolson (1972) plasma membrane contains about 50–60% proteins and 50–40% lipids. Lipids form a bilayer with hydrophilic heads pointing outwards
