## Plasma Membrane Structural Features: Educational Overview

### Task Instructions:
Drag the labels onto the diagram to identify structural features associated with the plasma membrane.

### Diagram Explanation:
The provided diagram illustrates the structural components of the plasma membrane, which is essential for maintaining cellular integrity and controlling the movement of substances in and out of the cell. 

Below are the structural features that need to be identified in the diagram:

1. **Extracellular Fluid**: This is the fluid environment outside the cell membrane, containing nutrients, ions, and signaling molecules.
   
2. **Glycocalyx**: A carbohydrate-enriched coating on the exterior surface of the cell membrane that aids in protection, cell recognition, and communication.
   
3. **Cytoplasm**: The internal fluid of the cell, which contains organelles, enzymes, and various molecules necessary for cellular function.

4. **Integral Proteins**: Proteins that are embedded within the lipid bilayer of the membrane and may span across it, playing key roles in transport, signaling, and structural support.

5. **Peripheral Proteins**: Proteins that are attached to the exterior or interior surfaces of the lipid bilayer, often associated with the integral proteins, and are involved in various cellular processes such as signaling and maintaining the cell's shape.

### Labels to be Placed on the Diagram:
- Extracellular fluid
- Glycocalyx
- Cytoplasm
- Integral proteins
- Peripheral proteins

### Diagram Description:
- **Extracellular Fluid**: Label should be placed in the region outside the membrane.
- **Glycocalyx**: Visible as a region with carbohydrate chains on the outer surface of the membrane.
- **Cytoplasm**: This label should be placed in the region inside the membrane.
- **Integral Proteins**: Visible as larger molecules that span through the lipid bilayer.
- **Peripheral Proteins**: Identifiable as proteins attached to the surfaces of the lipid bilayer, not spanning the entire membrane.

Submit your labeled diagram by dragging each label to its correct position.

### Interactive Learning:
Take a moment to reflect on the functions of each structure you identified and how they interact to maintain cellular homeostasis. Understanding these components will enhance your knowledge of cellular biology and its intricate mechanisms.
