Plant intelligence: The movement of plants. Scientific News 126
Although plants appear to be immobile beings, the truth is that they are endowed with intelligent movement
Although plants appear to be immobile beings, the truth is that they are endowed with intelligent movement: sunflowers, olive trees and ceibos:
- The movement of sunflowers, called heliocentrism, has a genetic basis and is due to the genetic mechanism of stem growth in such a way that they are endowed with the anatomical possibility of turning from east to west during the day and from west to east during the night, for having an unequal growth between the two sides of the stem.
Thus, plants mark the path of animal intelligence: first genetics, then anatomical structure and, finally, the ability to respond to environmental change.
- The olive tree and many other plants are also capable of orienting their leaves in daily cycles and following the climatic seasons, in order to obtain the best light conditions.To do this, like the sunflower, they must have anatomical structures in the petiole of the leaf and stem that allow them to turn slightly to respond to daily and seasonal changes in the position of the sun with respect to the olive tree.
- The ceibo is a tree that folds its leaves, sticking them to the trunk at night and taking them off during the day, due to a special structure of the petiole of its leaves.This anatomical base of genetic design allows it to react to thermal changes and the presence of predatory insects.
These intelligent attitudes in plants can be considered precursors of animal movements, as are the geotropism of the roots with the orientation to the body position coming from the snail of the animal ear.
