Plants do not have nervous systems and therefore they do not have the ability to feel pain or any other sensation as it is defined in animals. They are not capable of sensing or responding to stimuli in the way that animals do. They can respond to environmental changes, like light, touch, temperature, and humidity but these responses are controlled by hormones and biochemical reactions, not by a nervous system.
Plants have complex physiological processes that allow them to sense and respond to their environment, but these processes are not the same as feeling pain. For example, when a plant is touched, it may respond by bending away from the touch, but this is not because the plant feels pain, but because it is responding to a mechanical stimulus.
It is also important to note that plants do not have a central nervous system, which is the part of the nervous system that is responsible for the perception of pain in animals. They don’t have nerves, brains or any other type of organ that could be responsible for the sensation of pain.
So while plants do respond to environmental stimuli, they do not have the capacity to feel pain or experience suffering in the way that animals do.
