High speed and high resolution. Breakthrough ADC technology switches from 8 to 16 bits in the same oscilloscope.
The graph clearly shows that the humidity inside the polythene bag is increasing with time. This increase in humidity is due to the transpiration from the plant.
Not all scientists agree on the significance of transpiration. Transpiration was previously thought to provide the energy to move water in the plant and also to cool the plant. Now scientists believe that transpiration is just an unfortunate side-effect of the stomates' main function of absorbing carbon dioxide and expelling oxygen in photosynthesis.
