Trees are very important, valuable and necessary to our existence as they have furnished us with two important life essentials; food and oxygen. Apart from basically keeping us alive, there are many other little and big benefits we get from trees. So, trees are vital resources for the survival of all living beings. Therefore, Governments world over and many Organizations are taking steps to prevent deforestation and to tell the benefits of planting trees. Let us go through some important points about the Importance of trees for the existence of human life.Trees intakes Carbon dioxide from air and breathe out fresh oxygen for our life support. This cycle is made by nature to sustain other living beings. Further, the Carbon dioxide breathed in by the trees is one of the greenhouse gases. This and other greenhouse gases, when released into the atmosphere form a layer and trap the heat from the sun. They result in an increase in the atmospheric temperature. This causes global warming. So planting more trees will clean the air will reduce the global warming effect.
Answer:
A tree is a tall plant with a trunk and branches made of wood. Trees can live for many years. The oldest tree ever discovered is approximately 5,000 years old and the oldest tree from the UK is about 1,000. The four main parts of a tree are the roots, the trunk, the branches, and the leaves.
The roots of a tree are usually under the ground. However, this is not always true. The roots of the mangrove tree are often under water. A single tree has many roots. The roots carry nutrients and water from the ground through the trunk and branches to the leaves of the tree. They can also breathe in air. Sometimes, roots are specialized into aerial roots, which can also provide support, as is the case with the banyan tree.
The trunk is the main body of the tree. The trunk is covered with bark which protects it from damage. Branches grow from the trunk. They spread out so that the leaves can get more sunlight.
The leaves of a tree are green most of the time, but they can come in many colors, shapes and sizes. The leaves take in sunlight and use water and food from the roots to make the tree grow, and to reproduce.
Trees and shrubs take in water and carbon dioxide and give out oxygen with sunlight to form sugars. This is the opposite of what animals do in respiration. Plants also do some respiration using oxygen the way animals do. They need oxygen as well as carbon dioxide to live. Trees are renewable resources because, if cut down, other trees can grow in their place.
