Plants Can "Think and Remember"
When it comes to light, scientists have found that plants can "think" and "remember" in ways very similar to our own nervous system:
In their experiment, the scientists 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.
"We shone the light only on the bottom of the plant and we observed changes in the upper part," explained Professor Stanislaw Karpinski from the Warsaw University of Life Sciences in Poland, who led this research.
