==Plant interactions==
Plants can interact with one another in their environment through their root systems. Studies have demonstrated that plant-plant interaction occurs among root systems via the soil as a medium. Researchers have tested whether plants growing in ambient conditions would change their behavior if a nearby plant was exposed to drought conditions.<ref name=":2">{{cite book |last1=Chamovitz |first1=Daniel |title=What a Plant Knows: A Field Guide to the Senses: Updated and Expanded Edition |date=2017 |publisher=Farrar, Straus and Giroux |isbn=978-0-374-53712-8 |oclc=1041421612 }}{{page needed|date=January 2025}}</ref>
