Observation and Conclusion

Elizabeth Van Valkenburgh a professor of Biology at University of Washington presented a theory on this topic. She says" Plants and Trees feel, preserve as well as respond to a touch including painful touch. According to her, Plants also respond to physical disturbances like being cut or wounded, just as human body respond to pain. Pain is the defense mechanism in human your body. The pain system in human body depends on brain. But, as we know Plants do not have brain" There would be a quite quiet debate among the researchers for the topic' Weather Plants do or don't feel pain. Some researchers conclude that, There is similar reaction in plants as well as animals after applying anesthetics. But, Van Valkenburgh says that just because a plant can theoretically be numb doesn't mean that plants can feel pain or not. Physiology of plants would definitely change after applying anesthetic drug on them. Her Conclusion: There must be a different defense system in plants
