You asked us, can plants communicate? Well, not too long ago if you answered yes to that question most people would think you were crazy.

But growing evidence suggests that plants can actually communicate and in more ways than one. You see, plants don't have mouths, eyes or ears. However, they apparently see, feel, smell and possibly even hear signals from other plants. That sweet summer smell of freshly cut grass is actually a blast of chemical signals sent out by the injured grass, a warning to let other nearby plants know to go on the defensive.

Why would a plant want to give its competitors a heads up? What could the possible evolutionary benefit be? Well, some scientists think that plants aren't actually talking to each other but to themselves, while their nosy neighbors take advantage of the situation and eavesdrop.

At this point, there are more questions than answers, I admit. It's becoming clear though, that communication isn't limited to just animals like ourselves. Plants have a lot to say, too.

    I think that it is fascinating that plants can communicate. I previously knew that plants were able to communicate through a documentary but every time I hear this, its hard for me too process this. We live a crazy world!

    I didn't know that the smell of freshly cut grass was a warning to other plants because that is really cool actually. It's actually kinda sad because even though the plants get a warning that there gonna be killed they can't do anything about it.

    Did you know that other things besides animals can communicate? It was recently found that plants can communicate with each other. Plants, obviousley, don't have eyes, ears, noses,hands, or mouths, but they do have multiple ways to communicate with each other. The plants release chemicals that are registered by other plants as a warning. If a patch of grass is dieing it releases a certain smell, which is actually a release of chemicals. Those chemicals warn other plants to go on the defense. Scientists think that the plants atctually release the chenicals to warm themselves, bu that nearby plants reveive th warning inedvertantly. Scientists are still doing more tests to figure out exctly what the plants are doing and why.

    I thought this artivle was very interesting. I didn't know plants could communicate, if they don't have mouths to talk, ears to hear, or hands to write with, how can they communicate? It was very interesting for me to learn that a chemical reaction, or the release of certain cheiclas could translate into a plant language.

    I didn't know that plants can possibly communicate or even eavesdrop on other plants. Nether did I know that the injured grass can send out a chemical that means to other plants to be careful.

    I think it's cool that animals like ourselves and plants have a way of communication. Only what if we figured out the language, or what ever plant communication is called. I mean if scientists figured it out, maybe we could all communicate with plants. Just think about it... maybe you could "talk" with the plants in your garden. i think it would be a fantastic idea.

    This article is about plants and their ability to communicate with other plants. These plants do not talk, nor do they have eyes. However, they communicate in a different way that you would not have expected. Plants can feel, smell, see, and possibly even signal to other plants. I personally did not know any of this about plants. I did not think that plants have some of the same characteristics that us humans do, however now that I have learned this about our plants, I think it is very interesting and I would like to learn more about it in the future.

    "But growing evidence suggests that plants can actually communicate and in more ways than one. " Plants can apparently hear, feel, and smell signals from other plants, even though they don't have ears, eyes, or noses. Like grass, when the plant is cut, it releases a smell to 'warn' other plants. Scientists think that plants are talking to themselves and not other plants.

    This is a hard thing to believe because how could anything hear, see, or smell with the features giving it that ability. I think that this is partially true and partially false.

    I think that it is cool for plants to communicate but it is common to ants because if ants wanted help, they emit chemicals that would let the ants help other ants, a plant communicate in a different way if somebody cuts a grass, it emits a chemical causing the plants to go on to defensive. Well if plants could communicate that same way that ants do, I think that it might be awful if plants don't communicate.

    I am not too sure if plants can communicate but if they can that would be pretty cool. I have never thought about the fact that plants can communicate. It would actually be cool to understand what plants are trying to express. I don't really understand how they would communicate by smelling, hearing, and touching but if they can it would be interesting if they can actually tell others what they think.
