    researchers say the shamed grass drop experiment does not prove that plants have the ability to learn.a tree feel pain and loneliness when it collapses alone in no one else? Some experts gave a negative answer to the question.
    recently published in Trends in Plant Science, scientists can infer that plants are not conscious based on comparative studies of the brains of simple and complex animals. The purpose of this study is to explore the evolution of consciousness.
    previous study concluded that only vertebrates, arthropods, and vertebrates had brain structures that met the threshold of being conscious, while other animals were not. Since there are unconscious species in animals, plants without brains, not even neurons, are less likely to have consciousness. Lincoln Taiz, a retired professor and developmental biologist at the University of California, Santa Cruz, commented.
    since plant neurobiology officially became a field of study in 2006, there has been a lot of debate about whether plants can think, learn, and deliberately choose their own behavior. Some researchers have pointed out that plants are simply not likely to be the subject of neurobiological research.
    the greatest danger of anthropomorthic plants in the study: it undermines the objectivity of researchers. "Obviously, plants and animals have very different survival strategies in evolution. This organ of the brain is a luxury, and plants have to grow a highly complex nervous system is not really good for themselves.
    enthusiasts of plant neurobiology compared plant electrical signals with the animal's nervous system and found some similarities, but Taiz and other collaborators say the researchers described the brain as simple as a sponge in the comparison.
    function of plant electrical signals is to regulate the distribution of charged molecules on cell membranes and the long-distance transmission of information in plants. The first function allows the plant leaves to curl, which is achieved by regulating the ion movement, which causes water to flow out of the cell, thereby changing the shape of the cells, while the process by which a leaf reacts defensively to distant leaves after being bitten by an insect is the embodiment of the second function. Both behaviors of plants feel as if they are responding to external stimuli, but Taiz et al. stress that these reactions are genetically determined and are only the product of the survival of countless generations of naturally selected moderates.
    the authors hope that more experimental conditions and more rigorous experimental control research will be carried out in the future to clarify the outstanding problems in the current plant neurobiology experiments. (
