Question
______ is also known as cell membrane.
- Plasma membrane
- Nuclear membrane
- Cytosol membrane
- None of these
Hint:
The cell membrane usually surrounds the cytoplasm of the cell.
The correct answer is: Plasma membrane
- The plasma membrane is also known as the cell membrane.
- The cell consists of cytoplasm where all the reactions take place and all organelles reside. This cytoplasm is surrounded by a membrane that performs the function of protecting the cytoplasm and the inner contents of the cell. This membrane is known as the cell membrane. The other name of this layer is the plasma membrane or cytoplasmic membrane.
- It also helps in the transportation of molecules across it through transport proteins.
The cell membrane is semi-permeable in nature. It only allows certain molecules to pass through it and resists the movement of other molecules.
