Question: why do animals feel pain but plants don't?
Conversation
I know they don't have nervous systems. The question is why they ddnt need one. They do after all react to the environment. When giraffes eat acacia leaves they even release that info to other trees nearby with ethylene gas! This is pretty advanced, as is the 'root internet'

Recurring theme so far is they can't move so why bother feeling pain. But by this logic do snails feel less pain?

Feels like you’re thinking about evolution wrong. Pain is selected for as a trait if even slightly useful. It may become less useful or a spandrel if other adaptations drive trade offs like a heavy shell. Slow movement beats no movement (eg getting out of sun)

No, thiis is my current hypothesis too, but it wasn't satisfying enough. There are animals that are stationary too. Limpets have brains for example.
