What Effect Does a Cell's Overall Thickness Have on Its

What effect does a cell's overall thickness have on its permeability?

A) The cell's permeability is directly proportional to the thickness traversed.
B) As the cell's thickness increases, its permeability decreases.
C) As the cell's thickness increases, its permeability increases.
D) Only the cell's membrane thickness, not that of its cytoplasm, have an effect on its permeability.
E) The larger a cell becomes, the greater its proportional surface area, which increases the cell's permeability.
