Figure 1.

Electrical discharge in the Venus flytrap between electrodes located in a lobe (−) and a midrib (+) connected to a charged 4.7-μC capacitor and a NI-PXI-4071 digital multimeter. The length of the midrib was 2 cm. These results were reproduced 23 times on different Venus flytrap plants. The capacitor was disconnected (off), recharged, and connected again (on). U is the capacitor voltage in volts.
