The fluid mosaic model explains which aspects of a cell membrane ?

Options

A. Only structural aspects
B. Only functional aspects
C. Both structural and functional aspects
D. Only fluidity of membrane

Explanation

### Step-by-Step Solution:

1. **Understanding the Fluid Mosaic Model**: The fluid mosaic model is a widely accepted description of the structure of cell membranes. It illustrates how various components, such as proteins and lipids, are arranged within the membrane.

2. **Components of the Membrane**: The model highlights that the cell membrane is composed of a phospholipid bilayer with proteins, cholesterol, and carbohydrates embedded within it. This arrangement creates a "mosaic" effect.

3. **Fluidity of the Membrane**: The term "fluid" refers to the ability of the lipids and proteins to move laterally within the layer, allowing for flexibility and the dynamic nature of the membrane.

4. **Structural Aspects**: The fluid mosaic model explains the structural aspect of the cell membrane by showing how different molecules are organized and how their arrangement contributes to the overall integrity of the membrane.

5. **Functional Aspects**: The model also addresses the functional aspects, such as the selective permeability of the membrane, which allows certain substances to pass while blocking others. It explains how proteins function as receptors, channels, and transporters, facilitating communication and transport across the membrane.

6. **Conclusion**: Therefore, the fluid mosaic model explains both the structural and functional aspects of the cell membrane, making it a comprehensive model for understanding cell membrane dynamics.

### Final Answer:
The fluid mosaic model explains both structural and functional aspects of a cell membrane.
