What trees talk to each other

Trees constantly take information from their environment via the leaves and root tips, process it and act accordingly. They communicate in the organism and with each other.

Biologists and scientists have recognized that plants are able to much more than expected.

They are able to taste, smell, feel, hear and even see. Even if trees, shrubs and herbs have no sensory organs and no brain, they can take the signals from the environment, for example about the light and water.

Evidence of the communicative behavior of plants is proved worldwide.

The Italian plant neurologist Stefano Mancuso from the University of Florence speaks about the "intelligancy of plants". He arbues with other scientists that plants should be reexamined and given an appreciation in science.

"The general hierarchy of values banishes plants to the lowest level of living things," writes Mancuso. "An entire kingdom, the plant kingdom, is completely underestimated, although our survival and future on earth depend on it."

Smart roots?

The cell biologist Frantisek Baluska from the University of Bonn in Germany describes it as the "command center", the root tip for the perception of the plant.

He has researched targeted movement and sensivity of the root tip, thereby confirm Charles Darwin's "Root Brain Theory".

The discoverer of evolution compared the root tip of a plant with the brain of one of the "lower animals" in his pioneering book "The power of movement in plants". His observations were confirmed several times, but it was only 125 years after Darwin that Baluska a team of scientists from the universities of Bonn and Florence filmed the movement of the root tips.

It is clearly visible that the root tip creeps through the ground like a worm. The root tip perceives water or toxins, sends the messages via cells into the root, which then adjusts their direction as they grow.

The roots send messages from the ground to the leaves. And the leaves send information from the tree top to the roots and other leaves.

For example if the roots find too little water, they tell the leaves to close their openings, the stomata. Otherwise too much water would evaporate from the opened stomata .

Trees among each other

Trees communicate, they exchange information with each other and with other plants in their environment, with mushrooms and with animals. On this way plants find out whether predators such as deer or caterpillars are nearby.

The leaves communicate with each other from cell to cell when they get eaten or when an insect lays its eggs on the leaves. The tree then produces even more chemical substances ( such as tannin in oak leaves ) that scare away the predator or even poison it.
