Plant science considers plants passive organisms, not capable of cognition and behavior. Yet already in 1880 Charles and Francis Darwin had noted that this was an over-simplification. According to Karl Popper (1994), all life is problem-solving. Plant scientists today still maintain that plants perceive and process environmental information automatically, with no neuron-like sensory-motor systems and cognitive processes. Yet evidence is emerging that plants actively sense their environment and have sensory-motor systems that are sensitive to anesthetics. Hence some kind of sentience/consciousness may underlie their responsiveness to their sensory experiences and their capacity to control their plant-specific cognition and behavior.
