Are trees intelligent

What trees talk about

Cunning Root?

The cell biologist Frantisek Baluska from the University of Bonn calls it the “command center”, the tip of the roots for the perception of the plant. He researched targeted movement and sensitivity of the root tip, thereby confirming Charles Darwin's “root brain theory”. The discoverer of evolution compared the root tip with the "brain of one of the lower animals" in his groundbreaking book "The Power of Movement in Plants". His observations have been confirmed several times, but it was not until 125 years after Darwin that Baluska and a team of scientists from the Universities of Bonn and Florence filmed the movements of the root tip. It is clearly visible that the root tip crawls through the ground like a worm. The tip of the root perceives water or toxins, sends the messages via cells into the root, which then adapts its direction accordingly as it grows.

The roots send messages from the earth to the leaves above. And the leaves send information from the treetop to the roots and other leaves. For example, when the roots do not find enough water, they transmit to the leaves that they are closing their openings, the stomata. Otherwise too much water would evaporate from the open stomata.

Trees communicate, they exchange ideas with each other and with other plants in their environment, with mushrooms and with animals. In this way, trees inform themselves whether predators such as deer or caterpillars are in the vicinity. The leaves tell each other from cell to cell when they are 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 deter predators - or even poison them.
