Which statements are true? explain why or why not.
-4 A plant must be able to respond to changes in the water status of its surroundings. It does so by the flow of water molecules through water channels called aquapo- rins. The hydraulic conductivity of a single aquaporin is 4.4 × 10-22 m3 per second per MPa (megapascal) of pres- sure. What does this correspond to in terms of water mol- ecules per second at atmospheric pressure? [Atmospheric pressure is 0.1 MPa (1 bar) and the concentration of water is 55.5 M.]
