SCIENTISTS FILMED A PLANT COMMUNICATING 😱....
Scientists filmed a plant “communicating” with its neighbor using a sophisticated system of airborne compounds. These imperceptible chemical signals serve plants to repel herbivores and warn nearby plants of potential threats. While researchers have known these plant defenses since the 1980s, the mechanism behind how plants receive and respond to these signals remains a mystery.
To capture this footage, scientists used a bomb to transfer compounds emitted by damaged, insect-infested plants to healthy ones and used a fluorescence microscope to observe the reactions.
The experiments involved exposing the leaves of several plants to caterpillars and then monitoring the intact plants' responses to distress signals emitted by the injured. Plants communicate with each other as a survival strategy to defend themselves from threats and optimize their growth. They use a variety of chemical signals to convey information about environmental conditions, such as herbivore attacks or the presence of pathogens.
When a plant is under stress, it releases these signals into the air and neighboring plants notice them. This communication allows nearby plants to prepare for possible hazards by triggering defensive responses, such as the production of chemicals to deter herbivores or the strengthening of cell walls.
Plants can also communicate through underground networks of fungi called mycorrizas, which share nutrients and information about soil conditions. These communication mechanisms help plants adapt and thrive in an ever-changing environment
