The metaphor of the tree to describe the semantic progression of human speech. As we have completed our discussion of tree-climbing, the Christmas tree, and the evergreen, we now return to their ancestor subject branch, the tree. The largest recorded circumference of a tree's trunk is 46 meters. The evolution of the tree's vascular tissues and localized regions of cell division allowed the strengthening and conducting tissue to be dead, hollow, thick-walled tubes. Downward extensions of the tree provide anchorage and allow for sufficient water and fuel absorption.
Trees live without consciousness, without a mind.
They can live much longer, but can never move across the ground. Trees are vital in the creation and continuance of almost all life on Earth. They serve as food and shelter for many animals, they provide life-giving oxygen, and they fertilize soil. Sunlight, water, soil, carbon dioxide, oxygen, and nitrogen. Nitrogen is acquired from the soil via bacteria in the tree's roots.
