Answer: The cell membrane of a living plant cell ( selectively regulates the passage of substances into and out of the cell (option D). Explanation: The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier. The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell. At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.

D) It selectively regulates passage of materials into and out of the cell.

  • The plasma membrane in a living plant cell is composed of a double lipid layer that gives it hydrophobic character and acts as a semi- permeable barrier.
  • The partial permeability of the substances allows regulating the passage of substances from and to the interior of the cell.
  • At the level of the plasma membrane there are several mechanisms and transport to allow the entry of substances needed for the cell or the output of synthesized products or metabolic waste, thus regulating the passage of substance in a selective way.
  • They keep toxic substances out of the cell.
  • They contain receptors and channels that allow specific molecules, such as ions, nutrients, wastes, and metabolic products.

Therefore, correct option is D)
