Plants 'can think and remember'

Researchers believe that plants are capable of remembering and reacting to information contained in light.
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 on a side note, poor vegetarians, pretty soon they will have nothing to eat and will have to become one of those cult people who believe they can exist on air. lol, this was exactly my first thought when I read this article! Kinda throws their rationalization out the window, doesn't it now?

We already know that plants can go into shock, and now this. I think the vegetarians are going to lose the battle about not eating meat because it can feel pain - soon enough we will recognized the sheer agony of a plant being ripped from the earth to be consumed. They will probably make a machine that will not only read plants emotions, but record the screaming of the carrot as it is being consumed.

I don't really see any thinking on the part of the plants... If plants could think and respond to each other they would have killed us off long ago!

This may be a bit of a different sub-field, but I have some sort of a very thin vine that grows up through my hedges on the east facing side of my house. The hedges are about three feet tall, and when the vines reach the tops of the hedges and need something higher up to cling to, they seem to instinctively reach for the screens on the windows and seldome for the slicker brick face of my home. I have cut these vines numerous times and each time they regrow, they do not reach toward the light, but westward toward something to hang on to!! And they seem to sense where the screens are!

the only thing that is produced in nature to be consumed are fruits. fruits in this case being anything with seeds in or out side of the pod.
