An astonishing window into the inner world of plants reveals cutting-edge science in plant intelligence. Research shows that plants communicate, manipulate other species, and move in sophisticated ways. Although they lack brains, their internal systems resemble neuronal networks, allowing them to learn, remember, and behave in flexible, goal-directed manners. Paco Calvo, a leading figure in plant signaling and behavior, offers a fresh perspective on plant intelligence, utilizing tools from animal cognition studies to deepen our understanding. For instance, wild strawberries can learn to associate light intensity with nutrient levels, and flowers can time their pollen production to coincide with pollinator visits. Plants exhibit social intelligence by releasing chemicals to communicate and identify one another. They make growth decisions based on resource availability and even display individual preferences, suggesting they have personalities. Calvo also explores how plants inspire advancements in technology, from robotics to AI. Most importantly, he argues that recognizing plants as active participants in the climate crisis—rather than mere resources—can help us address urgent environmental challenges.
