What is cell membranes?
Understand the Problem
The question is asking for an explanation of what cell membranes are, likely regarding their structure and function within biological cells.
Answer
The cell membrane is a semipermeable membrane of lipids and proteins, regulating material transport and providing protection.
The cell membrane is a thin, semipermeable biological membrane that surrounds the interior of cells, composed mainly of a lipid bilayer and proteins. Its functions include regulating the transport of substances into and out of the cell and protecting the cell from the external environment.

More Information
Cell membranes are vital for maintaining cellular integrity and homeostasis, with selective permeability allowing specific substances to pass while blocking others.
Tips
A common mistake is confusing the cell membrane with the cell wall; the cell wall is an additional protective layer found in plants, bacteria, and fungi, whereas the cell membrane is present in all cells.
