Foe the Vegans out there....

Mostly the vegans that don't want to hurt a poor little animal... awwww..... How could us big bad hunters do that... Suspect hehehehe...

Just joking. lol!
Seriously, I did find this interesting.

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.

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.

He presented the findings at the Society for Experimental Biology's annual meeting in Prague, Czech Republic.

"And the changes proceeded when the light was off... This was a complete surprise."

In previous work, Professor Karpinski found that chemical signals could be passed throughout whole plants - allowing them to respond to and survive changes and stresses in their environment.

But in this new study, he and his colleagues discovered that when light stimulated a chemical reaction in one leaf cell, this caused a "cascade" of events and that this was immediately signalled to the rest of the plant by via specific type of cell called a "bundle sheath cell".

The scientists measured the electrical signals from these cells, which are present in every leaf. They likened the discovery to finding the plants' "nervous system".

Thinking plants

What was even more peculiar, Professor Karpinski said, was that the plants' responses changed depending on the colour of the light that was being shone on them.

"There were characteristic [changes] for red, blue and white light," he explained.

He suspected that the plants might use the information encoded in the light to stimulate protective chemical reactions. He and his colleagues examined this more closely by looking at the effect of different colours of light on the plants' immunity to disease.

"When we shone the light for on the plant for one hour and then infected it [with a virus or with bacteria] 24 hours after that light exposure, it resisted the infection," he explained.

"But when we infected the plant before shining the light, it could not build up resistance.

"[So the plant] has a specific memory for the light which builds its immunity against pathogens, and it can adjust to varying light conditions."

He said that plants used information encrypted in the light to immunise themselves against seasonal pathogens.

"Every day or week of the season has… a characteristic light quality," Professor Karpinski explained.

I'm not so much of a veggie eater. But the critters best look out!
