Proper Ways to Care for Landscape Trees
Friday, November 14th, 2008The components of a tree can be divided into three main parts: the root system, the leaves and the woody “skeleton” that connects them. The function of the root system is to provide the raw materials necessary for growth such as mineral salts, dissolved in water, to the tree. The leaves perform photosynthesis though the absorption of carbon dioxide from the surrounding air and using the energy from the sun, convert this into the simple sugars. These sugars are then combined with the moisture from the roots to give the tree its nutrients.
The trunk, limbs, branches and twigs act as the tree’s skeleton to hold the leaves in position so that they receive the life-giving sunlight and air. They are also used for transportation as they carry raw materials between the roots and leaves. Capillary attraction pulls up the materials absorbed through the roots and this is also assisted by the osmotic action induced by the evaporation of water from the leaves. This loss of water through the leaves is known as transpiration. On any summer day, a birch tree can transpire between 700 to 900 gallons of water.This is what causes the sap to continuously flow from the roots to the twigs at the very top of the tree.
