Question
Which of the following statements is incorrect?
- Plant and animal cells contain plasma membrane.
- Cell membrane has a bilipid layer.
- Plasma membrane is rigid.
- Cell membrane is flexible.
Hint:
The cell membrane is not a solid structure. It is made of millions of smaller molecules that create a flexible and porous container. Proteins and phospholipids make up most of the membrane structure.
The correct answer is: Plasma membrane is rigid.
- The long hydrocarbon chains of the fatty acids, therefore, move freely in the interior of the membrane, so the membrane itself is soft and flexible.
- In addition, both phospholipids and proteins are free to diffuse laterally within the membrane a property that is critical for many membrane functions.
