Plants DO talk !

Postby 2810712 » Wed Mar 16, 2005 11:30 am

Ya, they do [?]talk but electrically,
Many days before I saw on TV that there is a circuit in plant body i.e. whole body is a closed circuit. And if we cut one plant of say a species A , then some electrical changes occur in that plant, also some electrical changes ocur in other plants in that area, this area is much big.
so do plants really communicate , or these chnges are merely side effects of some other thing. I mean do they convey message or this is just what happens???
Also, why is there an electrical circuit in the plant body, does it play any IMP role in explaining HOH and mineral transport in tall plants ? ? ? Why is it created [ where is the cell ] ?
where is
-ve / +ve terminal ? ? ? Ohhh. soooomaaany qs. very less time, hummm


sorry for bad English,

yours faithfully,

What are these electrical circuits?
If you pull a plant out of the ground then of course there will be changes in the surrounding plants because you have caused a change in the soil and environment etc. Same with if you cut a part of the plant off. There will be a change in the air or environment and this will affect the surrounding plants. For a very brief period.
I cant explain it very much, but its just an idea.

I've been thinking recently. In todays scientific society if you want to be known by other scientists/media (or get on TV) then you have to either discover something amazing or say/research something strange/controversial. Researching something strange gets you on TV. For example - There are loads of strange stories now adays about mathematicians who have come up with a formula for whether a marriage will last etc (A formula for a good marriage, just one of the ones i remember). Crazy, but people waste time and money researching absolute rubbish.
Say your a plant scientist. Your not likely to make the news headlines are you? Unless you do some sketchy research and tell everyone that you have evidence that plants talk. What does everyone else think? Surely you can see what im trying to say?

Yes plants can comunnicate. In the forest when some danger occur to some plant, this plant can release a chemical substance which spread through air and other plants can catch it and be prepared for danger. This is all what i know about plant comunication.

How do plants prepare for danger? :?

They can start to produce defence substances against parasites or make stronger their protection by increasing of the production of these substances. I saw it on TV but i forgot about what exactly it was. But comunication of this kind surely exists.

I saw that plant communication on discovery or natgeo, I don't exactly remember .
What the changes in air and soil be, they are limited for smaller area , but that scientist found electrical changes[ voltage variation , as per I remember] in plants at a considerable distance.I think, if his discovery is irrespective of direction of air currents then it is true,
But, how is the circuit formed? ? ?
Is it due to mineral ions or whattype electron flow or ion flow circuit it is? ? ?
electron flow circuit is less likely to be there, I think.
Also, protozoan, what U told was an intraspecefic way. this is intra and inter both!!!

Plants can prepare for danger. But, I think release of chemical substances through air is not realistic!

Actually it is true. I have also heard of this

I heard tobacco plants can do this

Do you know what they as chemical substances are?

Link here.

<Excerpt>

This kind of communication is probably not unique to sagebrush and wild tobacco, but Karban says they do seem to be an especially well-matched pair. Sagebrush produces huge amounts of methyl jasmonate, the chemical that appears to trigger the defenses of many plants, including wild tobacco. When you cut a sagebrush plant, all that methyl jasmonate gets released into the air. In contrast, wild tobacco plants don't seem to react when other wild tobacco plants get chomped on, which makes sense when you consider that wild tobacco produces methyl jasmonate in relatively small quantities.
