The fluid mosaic model describes the plasma membrane as:

  1. A rigid, static, unchanging structure
  2. A protein-only layer
  3. A dynamic lipid-protein mosaic
  4. A carbohydrate-rich coating
Show answer and explanation

Correct answer: A dynamic lipid-protein mosaic

The fluid mosaic model emphasizes lateral movement of lipids and proteins. This provides flexibility and functionality to the membrane.
