During osmosis

• water moves from high to low concentration

• large or oddly shaped molecules move across a cell membrane

• water moves when energy is used

• proteins are built

What is the definition of Selective Permeability?

• The movement of materials across the cell membrane that requires NO ENERGY from the cell.

• The movement of materials through (or across) the cell membrane

• The ability of the cell membrane to allow some things to pass through while preventing other things from passing through.

• The movement of molecules from an area of high concentration to a area of low concentration
