Question
All cells contain cell membranes. Which of the following describes the composition of cell membranes?

The correct answer is:
**c
Cell membranes are composed of lipid molecules, which provide a flexible structure.**
Cell membranes primarily consist of a phospholipid bilayer, which allows for fluidity and flexibility. They also contain proteins, cholesterol, and carbohydrates, but the key feature of the membrane's structure and function is the lipid composition.
