Over the recent years, a small but growing group of researchers from Austria, Germany, Italy, UK, Japan, South Africa and the USA, has developed a new scientific field of research: the neurobiology of plants. Their discoveries question our perception of the limits between the animal and the vegetable reign: plants are capable of developing the cognitive process claimed by humans and animals.
Plants are able to sense their environment and to remember information provided by their perceptions. They are consequently able to react. Some are even able to communicate and develop a common defence against predators. This is the case of the Acacia trees in South Africa, for example, against predators like kudus. The communication among the Acacia trees happens through the emission of the ethylene a very light gas, small, colourless, odourless gas. When kudus start over grazing an acacia, the tree emits ethylene. When it gets to leaves of other trees, it affects the mitochondria and the mitochondria then produces the enzymes that catalyse the production for more tannin. And the tannin can be create digestion problems to the kudus even the death.
If plants can move, and feel could they possibly think? In a creative and captivating scientific investigation style, through spectacular specialist photography and CGI, and re-creating scientific experiments, this documentary is bound to change your own perception of plants.
