Plants don’t feel pain the same way humans do. They have some sort of nervous system that is sensitive enough to respond to chemical changes caused by pricking or cutting. But that doesn’t mean they don’t feel something. Some have even been known to express feelings of distress when their roots are being disturbed. Some have even been known to show affection to their owners, which is thought to be a response to something positive or pleasant rather than something negative or painful.
Plants can feel pain, new research suggests. In a study of Arabidopsis, a plant often used in research, scientists found that altering the levels of specific chemicals in the plant could mimic the feeling of being touched or cut. The research could help researchers better understand the way plants are affected by external stimuli, such as light and heat, and could help them improve the conditions of crops in production and in the wild.
Plants don’t feel pain the way people do. But new research shows that plants also experience other forms of sensitivity and reacted to stimuli in much the same way as animals when they were tested. The findings, which challenge the long-held view that plants are “immune” to pain, could have significant implications for the way we grow our food and medicine.
Research has shown cannabis plants can still function even if their roots are removed from the soil. They will continue to produce buds until they run out of water. In this case, the roots were taken out but the rest of the plant remained inside its container.
In conclusion, cannabis plants can sense heat and cold, but these sensations have no affect on them.
