Draw a model of the plasma membrane to form a cell. Include a tube embedded in the membrane. Show 2 water molecules inside the cell and 12 water molecules outside the cell. Indicate which way the water will move through the aquaporin with an arrow. a) Using your knowledge of membrane transport, which direction will the water molecules move through the aquaporin? Why? b) Why would water have a difficult time crossing the cell membrane? Keep in mind the structure of water in your answer. 2) Develop an explanation for the necessity of
