What characteristic would you expect to see in an epithelium that was specialized for passive diffusion of materials from one fluid to another?
A) a single layer of flattened cells
B) many layers of cells stacked together
C) large, cube-shaped cells
D) loosely connected cells surrounded by an extracellular matrix
