The electric nervous system of plants

What are plants talking about? – According to Swiss researchers Mousavi and Chauvin, the nervous system of animals are capable of sending electrical signals at speeds up to 100 metre per second.

Plants do this at speeds up to 3 metre per second. This means that a tree in the Netherlands can send a message throughout the country in less than 2 hours and a tree in the south of Germany can send a message in a bit more than one day throughout Europe. If a tree in Paris, France, would want to send a message to a tree in Shanghai, China, then this would take about 4 days.

The answer to the question ‘what are plants talking about?’, is still a mystery.
