cell membrane
Understand the Problem
The question is asking for information about the cell membrane, which is a vital structure in biology. The specific aspects may include its composition, functions, or significance in cellular processes.
Answer
The cell membrane separates the interior of the cell from the outside environment and regulates material transport.
The cell membrane, also known as the plasma membrane, separates the interior of the cell from the outside environment and regulates the transport of materials entering and exiting the cell.

The cell membrane, also known as the plasma membrane, separates the interior of the cell from the outside environment and regulates the transport of materials entering and exiting the cell.
More Information
The cell membrane is composed of a lipid bilayer, making it semi-permeable. This feature is crucial for maintaining cellular homeostasis, allowing certain molecules to pass while blocking others.
Tips
A common mistake is confusing the cell membrane with the cell wall, which is present only in plant cells, fungi, and some bacteria, providing additional support and protection.
