Plants use electrical-chemical means to convey touch information between cells. Unlike animals, there is no specialized tissue in plants for information conduction; instead, communication occurs through chemical signals diffusing between cells.
What is the role of electrical-chemical communication in plant movement, and how does it differ from animals?

In plant movement, electrical-chemical communication involves the transmission of signals in response to environmental stimuli. When stimulated, ion movements generate electrical impulses, enabling rapid responses like the closing of Venus flytrap leaves. Unlike animals, plants lack a nervous system, and their electrical signals are typically slower and lack the specialized cells found in animal neurons. Plant communication relies on ion fluxes, membrane potentials, and signal transduction pathways. While both use electrical signals, plants employ a different mechanism based on cellular and tissue responses, highlighting the diverse strategies organisms have evolved to sense and respond to their surroundings.
