Question
Which of the following helps in the transport of material across the membrane?
- Cell membrane
- Cell wall
- Cytoplasm
- Nucleus
Hint:
The barrier of the cell ensures the movement of different molecules inside the cell.
The correct answer is: Cell membrane
- The cell membrane helps in the transport of material across the membrane.
- The cells of all organisms are surrounded by a membrane that protects them from the outer environment. This membrane is known as the cell membrane. It also helps in keeping a static environment of homeostasis inside the cell.
- There is a special property of cell membrane and that is its semi-permeable nature. This nature allows only the selected number and type of molecules to move across the cell membrane from the outside to the inside. It consists of certain transporters which allow the transportation of molecules into the cell.
The cell membrane is also known as the plasma membrane or cytoplasmic membrane.
