Plants make poisonous chemicals to protect themselves from being eaten.
Scientific Claim
Plants produce a variety of natural chemical compounds as defensive mechanisms against herbivores and pathogens.
Original Statement
“Every single plant has a long list of toxic compounds that the plant uses to defend itself.”

Scientists found that old types of broccoli had more genetic variety than modern ones, and many of those lost genes help the plant make natural chemicals to fight off bugs and diseases—so yes, plants make these chemicals to protect themselves.
Plants make chemicals like tannins and oxalates to protect themselves from being eaten or infected, and this study confirms those chemicals exist—even if it’s asking whether they’re bad for people.
Unknown Title
Plants make their own natural poisons to keep animals and germs from eating them, and this study says most of the pesticide residue in our food comes from these plant-made chemicals, not human-made ones.
This study shows that certain plants release smelly chemicals to scare away animals that try to eat them, which is exactly what the claim says plants do.
Technical explanation
This paper directly demonstrates that Piperales plants produce volatile organic compounds (VOCs) as a conserved chemical defense strategy specifically targeting herbivorous mammals, aligning exactly with the assertion that plants produce natural chemical compounds as defensive mechanisms against herbivores.
All plants have built-in chemical weapons to fight bugs and germs, and they put more of them where they’re needed most—like on new leaves or flowers.
Technical explanation
This paper explicitly states that plants are 'well stocked with chemical defense compounds that function in protection against herbivores and pathogens,' directly confirming the assertion with broad evidence across plant species.
