2 vesicle. The osmotic flow could be reversed by a sufficient concentration of a different nonexchangeable protein species B outside the membrane. The osmotic flow could be reversed because at low concentrations each distinguishable species of nonexchangeable component reduces the chemical potential independently of every other species. 16.14) Osmosis in plants. Plants must lift water from ground level to their leaves. Consider the roots as a capillary with radius 0.01cm whose walls are a semipermeable membrane with pure water on the outside and a solution inside with solute mole fraction x = 0.001. The solution inside has density 1 g cm-3. What is the height of the solution at room temperature? For the ideal solution given, the osmotic pressure π across a membrane with chemical potential difference ∆µ is given by: ∆µ = πν where ν is the molar volume of the solute. (equation 16.31 in text) And, from the equation on the bottom of page 292 (derived from equation 16.39), and
