Electrical signaling is ubiquitous across life domains. We have previously demonstrated the presence of wound or tactile electrophysiological responses in a variety of both rapid movement (Sensitive Mimosa, Venus Flytrap) and non-rapid movement plants (Tomato, Mint, Rosemary, etc.). Here, we measured the conduction velocity of impulse propagation in the same group of species plus others. We found that conduction velocities in rapid movement plants are 3 times faster (~30 mm/s) than non rapid-movement (~5-10 mm/s). We also note that plant conduction velocities are up to 10,000x slower than neuron conduction velocities (1-90 m/s). Whether plant impulse propagation is passive or active is an area of continued investigation.
