Plants exchange warnings through distributed chemical signals without any central brain
Evidence
When a plant is attacked — by insects, by drought, by disease — it releases volatile organic compounds (VOCs) through its stomata. Neighboring plants receive these compounds through their own stomata and respond by activating defense genes before they themselves are attacked. The system is not centralized. There is no plant brain sending the signal. The warning is a distributed process: each plant both receives and retransmits, creating a propagating wave of defensive preparation across a meadow or forest. … But the receiving plant is not passive. It “decides” (in a chemical sense) how to interpret the signal based on its own condition — a well-resourced plant mounts a full defense; a stressed plant mounts a partial one and passes the warning further along. The network adjusts its response collectively based on the aggregate condition of its members. — Jamal Awil, The Whispering Archive, 162
