Question

what is cell membrane ? ​

Answer 1

Answer:

The cell membrane is a biological membrane that separates the interior of all cells from the outside environment which protects the cell from its environment. The cell membrane consists of a lipid bilayer, including cholesterols that sit between phospholipids to maintain their fluidity at various temperatures. 

Answer 2

• The cell membrane, also known as the plasma membrane, is a thin membrane that surrounds each live cell and separates it from its surroundings.
• The cell's components, frequently big, water-soluble, highly charged molecules including proteins, nucleic acids, carbohydrates, and chemicals involved in cellular metabolism, are enclosed by this cell membrane .
• Ions, acids, and alkalis that are harmful to the cell can be found in the surrounding water-based environment, as well as nutrients that the cell needs to survive and flourish.
• As a result, the cell membrane serves two purposes: first, as a barrier that keeps cell constituents in while keeping undesired things out, and second, as a gate that allows important nutrients to enter the cell while permitting waste products to exit.
