In terms of permeability, the cell wall and plasmalemma are
Open in App
Solution
The correct option is B Permeable and differentially permeable respectively
The cell wall is dead at maturity in plants. Hence, cell wall cannot regulate entry or exit of solute or solvent particles across it. In other words, the cell wall is fully permeable to both solute and solvent molecules. The plasma membrane is a living fluid membrane and separates cellular contents from the external environment. The traffic of molecules through plasma membrane is regulated. The plasma membrane is thus differentially permeable because it differentiates among solute particles and allows entry to only selected solute particles. In general plasma membrane is permeable to lipophilic substances and impermeable to hydrophilic substances.
