plant intelligence

Plant intelligence refers to a plant’s ability to perceive, respond to, and sometimes anticipate environmental changes. Although they lack brains or nervous systems, plants use complex signaling mechanisms—like chemical and electrical signals—to adapt to their surroundings. For example, they can sense light, gravity, and touch, adjusting growth accordingly. Some plants even communicate with each other and enlist helpful insects for defense. This shows that plants exhibit a form of adaptive "behavior," enabling them to survive and thrive in dynamic environments through intricate internal processes that many consider a form of intelligence.
