B
semipermeability
C
differential permeability
D
impermeability
Answer
complete permeability
Explanation
Solution
A cell wall is a tough and flexible layer surrounding the cell membranein plants, algae, and most prokaryotes. The cell wall shows complete permeability as it helps to transport substances in and out of the cell.
