Plants 'can think and remember'
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, the scientists showed that light shone on to one leaf caused the whole plant to respond.

Zitat:
Acacia plant controls ants with chemical
n Africa and in the tropics, armies of tiny creatures make the twisting stems of acacia plants their homes.
Aggressive, stinging ants feed on the sugary nectar the plant provides and live in nests protected by its thick bark.
This is the world of "ant guards".
The acacias might appear overrun by them, but the plants have the ants wrapped around their little stems.
These same plants that provide shelter and produce nourishing nectar to feed the insects also make chemicals that send them into a defensive frenzy, forcing them into retreat.
