Do Plants Have Feelings? One of the main distinctions between plants and animals is how they respond to stimuli. Humans have brains, where stimuli are understood and responses formed. “Emotional” responses are merely complex responses to complex social stimuli. Plants lack a central nervous system but are still capable of processing information from external sources and responding to them. While plants don't have the same “feelings” that we do, they often remember stimuli and communicate with other plants about them. Plant vs. Animal Feelings Animals have neurons that transmit sensory feelings to a central nervous system (the brain). In humans, if your brain determines that those feelings are negative and dangerous, it sends a message back to their point of origin, causing you to react to avoid the continuation of that pain. Animals like us have memories that allow us to avoid future pain. Memories of previous injuries don't trigger our bodies to produce adrenaline when the mem
