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.
In their experiment, scientists from the Warsaw University of Life Sciences in Poland showed that light shone on to one leaf caused the whole plant to respond. 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.
