noun. the state of being permeable to dissolved compounds, liquids, or gases. A perfect membrane hasn't any permeability, but the majority of all biological membranes are selectively or semi- permeable, allowing the selective passage of particular compounds, like the movement of nutrients through a cell membrane.

PERMEABILITY: "The cell's permeability will be the ultimate determinant of it's fate."
