Question
Which of the following statement is incorrect?
- Plant and animal cell contain plasma membrane.
- Cell membrane has bilipid layer.
- Plasma membrane is rigid.
- Cell membrane is flexible.
Hint:
The cell required fluidity too to function in an accurate manner.
The correct answer is: Plasma membrane is rigid.
- The incorrect statement here is that the plasma membrane is rigid.
- The plasma membrane is a layer of membrane surrounding the cytoplasm of the cell which performs various functions to keep the cell protected. It maintains the homeostasis of the cell, encourages communication between other cells, maintains potential, etc.
- It is also known to provide fluidity and not rigidity to the cell. The plasma membrane consists of lipids and out of these lipids, the majority is occupied by cholesterol. This particular compound is known for giving proper fluidity and shape to the cell.
The cell membrane maintains electric or cell potential. This feature is required for proper communication between two cells, or cells and its outer environment.
