People who claim that plants are conscious and emotional usually cite American Baxter's experiment  Baxter connects a lie detector to the leaves of a pot of plants  The design principle of this lie detector is that when people lie, their skin will sweat due to tension, resulting in lower skin resistance  By measuring the change of skin resistance, we can identify other people's emotions, Then judge whether people are lying  Baxter reported that in the experiment, when the subject thought of I'm going to burn that leaf, the lie detector reacted violently, the pointer suddenly moved to the top of the instrument and showed continuous fierce fluctuations  The lie detector drew a figure similar to that people would appear in extreme fear
Only creatures with central nervous system have consciousness and feelings. Plants have no nervous system
