i saw on the mythbusters that plants can sense people.
they hooked up a lie detector and this one guy thought of burning the plant and the lie detector thing went up it was cool. one day your plants will get you
There is a lot more to this. I wouldn't know about plants reading humans' thoughts, but plants do greatly react to our presence. That old question of "If a tree falls in the woods and no one is around to hear it, does it make a sound?" should be familiar. It does indeed make a sound (although, there is no one there to hear it, of course), but the sound it makes is different because in presence of humans, plants--especially trees--tense up. In absence of humans, trees tend to be more flexible. I've heard recordings from experiments in a study on this, and a falling tree sounds more like wind in absence of humans, rather than that creaky-snappy business that you might have heard if you've ever seen a tree fall. It's really interesting, actually.
I really wonder what kind of stimulus receptors that plants have that allow them to be able to sense us like they do. I'm not quite sure if this whole thing is limited to just humans, or any wildlife either. If I were more interested in botany, it would definitely be something I'd study.
