Plants feel pain

Last reviewed: January 10, 2026

Quick Answer

Plants lack the nervous system, brain, and nociceptors required for pain experience. They respond to stimuli through chemical signaling, but response does not equal suffering. Even if plants could suffer, eating them directly causes less plant death than feeding crops to livestock.

Evidence Summary

The claim: "Plants feel pain too, so eating plants is just as bad as eating animals." Why this is scientifically unfounded: Plants lack the biological requirements for pain:

No central nervous system
No brain or pain-processing regions
No nociceptors (pain receptors)
No evolutionary reason to feel pain (can't flee predators) Response ≠ Experience:
Plants respond to stimuli (light, gravity, damage)
A thermostat "responds" to temperature but doesn't experience cold
