You might not hear it, but plants are always talking. Through underground networks, airborne chemicals, and even electrical pulses, plants can “communicate” in ways science is still uncovering.

Volatile Organic Compounds (VOCs) are one way plants signal. When a plant is under attack by insects, it can release VOCs into the air, warning neighboring plants to activate their defenses.

In the soil, mycorrhizal fungi connect plant roots to form a "wood wide web." This underground network helps share water, nutrients, and chemical messages between trees and plants.

Some plants emit signals that attract predators of the insects feeding on them. Others can even adjust their growth direction based on signals received from nearby plants.

Plant communication shows that these organisms are more intelligent and connected than we once thought. Understanding these systems can help in sustainable agriculture and environmental protection.
