The cell membrane is described as a ‘fluid mosaic’. What does ‘mosaic’ refer to in this model?

A. The dynamic movement of lipids
B. The pattern of proteins embedded in the bilayer
✓
C. The presence of cholesterol in the core
D. The selective permeability of the membrane

📝 Explanation

The mosaic aspect describes the heterogeneous arrangement of proteins scattered throughout the phospholipid bilayer.
