It is mentioned in Mahabharata that plants also have five senses and also experience pleasure and pain. I am focusing on pain part only in this question.
As one can suck up water through a bent lotus-stalk, trees also, with the aid of the wind, drink through their roots. They are susceptible of pleasure and pain, and grow when cut or lopped off. From these circumstances I see that trees have life. They are not inanimate.
Recent studies may also suggest the same.
Do any other scriptures also says that plant experiences pain?
