Plants though silent exhibit a sophisticated communication system crucial for their survival functioning through chemical signals and underground networks. 

  • Chemical Warning System: Plants release volatile organic compounds (VOCs) when threatened by herbivores or other dangers.  
    • These airborne and soil-borne signals alert neighbouring plants to prepare defensive mechanisms like producing toxins. 
    • VOCs can travel through the air and soil, allowing communication over considerable distances to protect plants. 
  • Wood Wide Web: Through symbiotic relationships with mycorrhizal fungi, plants form an underground network called “wood wide web.”  
    • This fungal network facilitates nutrient exchange and distress signals, helping plants collectively respond to droughts or pests. 
  • Cooperation and Support: Plants share nutrients to aid struggling neighbours, especially in resource-scarce environments like dense forests 
    • This cooperative behaviour fosters ecosystem resilience and enhances overall forest health.
