The internal membrane refers to membranes that are found within the cell, such as the nuclear membrane, endoplasmic reticulum, Golgi apparatus, and mitochondria. These membranes help to compartmentalize the cell and regulate the movement of molecules in and out of organelles.
On the other hand, the plasma membrane, also known as the cell membrane, is the outermost membrane of a cell that separates the cell's internal environment from the external environment. It is composed of a phospholipid bilayer with embedded proteins that regulate the passage of molecules in and out of the cell. The plasma membrane is essential for maintaining the cell's integrity and allowing for communication with the external environment.

Internal Membrane
- Structure:
- Consists of phospholipid bilayer with embedded proteins
- Location:
- Found within the cytoplasm of cells, forming various organelles
- Function:
- Compartmentalizes cell functions by enclosing organelles (e.g., endoplasmic reticulum, Golgi apparatus, mitochondria)
- Provides specialized microenvironments for specific biochemical reactions
Plasma Membrane
- Structure:
- Consists of phospholipid bilayer with embedded proteins, carbohydrates, and cholesterol
- Location:
- Forms the outermost boundary of the cell
- Function:
- Regulates the entry and exit of substances into and out of the cell
- Maintains cell shape and integrity
- Facilitates cell signaling and communication
- Provides a barrier against external threats (e.g., pathogens)
Key Differences
| Feature | Internal Membrane | Plasma Membrane |
|---|---|---|
| Location | Within cytoplasm | Outermost boundary of cell |
| Function | Compartmentalization and microenvironment | Regulation of cell exchange and protection |
| Composition | Phospholipid bilayer with embedded proteins | Phospholipid bilayer with proteins, carbohydrates, and cholesterol |
| Significance | Enables specialized functions within organelles | Maintains cell homeostasis, integrity, and communication |
