Can Plants Feel Things ?
The Truth About Plant Sensitivity

Plants are incredible living organisms that play a vital role in sustaining life on our planet. While they lack a nervous system and brain, recent studies have shown that they have a surprising degree of sensitivity and even exhibit behaviors that closely resemble those of animals.
Plant Response to Stimuli
Recent research shows that certain plants exhibit a direct response to touch. For instance, Mimosa pudica, popularly known as the “sensitive plant,” has a unique way of responding to touch or vibration. The leaves of the plant fold inwards and droop, as if recoiling in response to a physical stimulus. Similarly, plants respond to light, with some having the ability to grow towards it when present and away from it when not.
Plant Communication
Plants can communicate with each other via chemical signals, passing important information to each other about potential threats and opportunities in their environment. For instance, in case of insect attacks, plants can produce volatile organic chemicals that can attract predator insects to help deal with the problem. This chemical communication allows the plants to coordinate responses and react accordingly.
“The idea that plants are conscious, let alone intelligent, is difficult to imagine from our human-centered perspective. Nevertheless, we, as well as other animals, rely on plants for our survival, exchanging CO2 for oxygen and consuming plants for food.” — Sandra Rehan, Ecology, Evolution and Organismal Biology professor at UNH.
Plant Sensitivity vs Animal Pain
While plants have been found to exhibit behaviors that suggest some degree of sensitivity, it is unlikely that plants feel pain like animals and humans do. Pain is a subjective experience that requires a nervous system and brain. However, plants’ experience of the world around them is undoubtedly different from that of humans and animals.
Regardless of whether plants feel things like animals and humans do, there’s no denying that they play an essential role in our ecosystems. As study author Prof. Alpi notes, “We’re beginning to understand that plants aren’t just inert organisms rooted in soils, but ones that are actually dynamic and communicate with other organisms in quite a sophisticated way.”
