Plants are able to "remember" and "react" to information contained in light, according to researchers.
Plants, scientists say, transmit information about light intensity and quality from leaf to leaf in a very similar way to our own nervous systems. These "electro-chemical signals" are carried by cells that act as "nerves" of the plants. And the response, which took the form of light-induced chemical reactions in the leaves, continued in the dark. This showed, they said, that the plant "remembered" the information encoded in light.
The next thing we want to know is if plants dream of light.
