The tree trunk, limbs, branches and twigs support the position of leaves so that they can get air and light. However, they also act as a transportation system, and carry raw materials from the leaves to the roots and vice versa. Materials that are absorbed by the roots are pulled upward by the assistance of capillaries and osmosis induced by water evaporation. Losing water through leaves is called transpiration.
