All these properties exhibit the capacitative characteristic of botanical tissue. Since Ohm's law depicts that all materials have obstruction to the electric current, the biological electrical characteristics of a botanical tissue can also be imitated to be an equivalent model with the resistance and capacitor connected in series or parallel. The relation between the phase angle and impedance measured is used to study and decide the integrality of the cell and the trend of the physiological status of a growing organism prospectively.
