Question

Cellular component that is responsible for exchange of substances into and outside the cell

• A. Cell membrane
• B. Cytoplasm
• C. Mitochondria
• D. Vacuoles

Answer 1

The correct option is A Cell membrane

• The cell membrane (also known as the plasma membrane (PM) or cytoplasmic membrane) is a biological membrane that separates the interior of all cells from the outside environment (the extracellular space) which protects the cell from its environment.
• It controls the movement of substances in and out of cells and organelles. In this way, it is selectively permeable to ions and organic molecules.
  
• Hence Cellular component that is responsible for the exchange of substances into and outside the cell is cell membrane.
• So, the correct answer is 'Cell membrane'.
