// hc; groot can feel physical pain, but only in a limited sense. there’s a certain misconception that because plants are able to feel touch and damage, that they are able to feel pain; however, pain is for the most part a product of human cognition and the perception of damage signals by the brain.
groot is a sentient plant; he most definitely possesses cognitive and functional skills associated with a higher neurological system ( that which is absent in plants ). so he has the potential to feel pain, but his brain doesn’t perceive pain –––– this is something he learns from being around other beings of the galaxy, and rocket, who lives with pain. he learns that pain is something that happens when you injure yourself, or when someone injures you, and that it’s a fear response that protects you from danger; and so he’ll come to feel it, to an extent. mostly he’ll just whine about it, much to rocket’s annoyance.
and yet, despite his resilience physically, he feels emotional pain very strongly.
