Fluid: phospholipid bilayer in which individual phospholipids can move = membrane has flexible shape
Mosaic: extrinsic & intrinsic proteins of different sizes and shapes embedded
2

Cholesterol: steroid molecule in some plasma membranes: connects phospholipids & reduces fluidity to make bilayer more stable
Glycolipids: cell signalling & cell recognition
