Plants can actually speak and listen

The forest is filled with the noise of life, although these sounds are often too high or low for the human ear, and we do not notice how animals and insects communicate with one another by means of vibration. Even the grass and the trees emit a hissing sound, comparable with bubbling tiny air bubbles in the gutters. Moreover, there is evidence that plants and insects can hear each other. Bees buzz at the desired frequency to release the stigma of flowering plants and beetles can catch the sound of air bubbles inside the barrel - an allusion to the fact that the trees survive the drought.

Scientists from the University of Western Australia in Crawley suggested that even bacteria can again serve each other beeps, then why plants do not do the same? Head of research Monica Gagliano and her colleagues found that the roots of maize seedlings, "purr" at a frequency of 220 hertz. Chili seedlings began to grow faster when there was a dangerous fennel. Thus boxes chili and dill were designed so that in close proximity to transmit only sound, but no odor. Such examples are many typed.

Scientists have found that plants do respond to sound and use it for communication. There he is when the leaves open pores to absorb the carbon dioxide and at the same time lose a large amount of water. To compensate for the loss of roots suck the moisture out of the ground, and then sends it back into the air via tubes called xylem. As such they represent a membrane with two way valves, each of which is connected to thousands of tiny tubes. The drier the soil, the tensions, "buzzing" the wood, and the more air bubbles are drawn through the membrane, while uttering a sound. For some plants this process is harmful, because gas bubbles blocking the water flow.

Communicate with each other forest plants are using spawn - similar to the way we use the Internet. As to the hearing, the hearing literally plants can not. Rather, they perceive the vibration of neighboring plants and wind.
