If you really listen, can you hear the plants speak? This researcher says yes.
At the University of Sydney, Gagliano researches whether plants can learn behaviors and communicate with one another about survival skills, such as accessing water and fending off predators. In one study, she noted that the mimosa pudica, a plant which contracts when touched, stopped responding after being repeatedly exposed to non-harmful foam. The plant altered its behavior not because it was tiring, but because it had learned not to fear the foam. Other plant scholars, such as Michael Pollan, have praised her work, acknowledging that there is much we still do not know about the flora around us. Critics, however, have warned against upsetting their understanding that consciousness and intelligence require the nexus of a brain.
