Final answer:
The organelle represented by the fluid mosaic model is the cell membrane. It is a fluid lipid bilayer with embedded proteins that functions in selective permeability and maintaining cellular homeostasis.
Step-by-step explanation:
The organelle represented by the fluid mosaic model is the cell membrane. The fluid mosaic model is a representation of the structure of the cell membrane, showing that it is made up of a fluid lipid bilayer with embedded proteins that are constantly moving and shifting. This model helps to explain how the cell membrane functions in selective permeability and maintaining cellular homeostasis.
