    The graph below shows the relationship between diameter of stomatal aperture and rate of transpiration in still air and in moving air. At which point on the graph is the rate of transpiration independent of stomatal aperture?

    A) A or E  

    B)        C

    C) D                     

    D)        B

    Correct Answer: B

    Solution :

    [b] Under still air conditions from point C, the rate of stomatal transpiration remains constant. This is because the air immediately surrounding the stomatal aperture is not removed by moving air. Thus, even when the stomata are fully open, transpiration will not increase.
