Most of the people today prefer to live in cities where high-rise buildings, traffic lights, and busy streets are flourishing. But even if these modern architectures and technologies have already replaced the rich land and forests of long ago, it is still essential that there are trees or any kind of plant within the area. Trees and all plants are important for all humans and animals to survive in this planet.

All kinds of trees are known as perennial plants. When properly taken care of, it can live for at least 2 years or more. Unlike other kinds of plants, most of the trees can live for long years. There are even some trees that can live for more than 100 years. And there are also some trees that can actually live for at least a thousand years or even more.

Trees are woody plants that are made up of numerous branches which are supported by a single sturdy trunk. There are different kinds of trees and each has its own characteristics. They all differ in height, shape, sizes, and the appearance of the leaves of the trees as well. But according to the experts, before a woody plant can be considered as a tree, it must be at least 3 meters up to 6 meters high by the time it reached its maturity. Aside from that, the trunk diameter of the woody plant must also be at least 10 centimeters so that it can be one of the perennial woody plants. On the other hand, if it does not meet the said requirements yet the plant is still made up of several stems, it is then called as a shrub.

In order for humans and animals to breathe fresh air, there must be trees surrounding the area where they live in. It produces the amount of oxygen which is the primary element if you want to survive in this planet. Aside from that, the trees also play an important role in reducing the amount of carbon dioxide as well. With the help of the trees, the temperature of the ground will also be cooler at the same time.

This type of plant is one of the most essential components that make up the natural landscape. It can prevent the erosion of the land and protect the people from landslides. Other than being soil holders and great part of the agriculture industry, trees are also used in designing as well as adding aesthetic appeal at the same time.

There are five different branches of a tree namely the leaves, the twigs, the branches, the trunk, and the roots. The latter part of the tree is the one that serves as the anchor so that the earth can get hold of the plant. The root also is the one that is responsible for absorbing the nutrients and water from the soil. The leaves are the ones doing to all the carbon dioxide to oxygen conversion and the rest of the parts hold the leaves so that it can get the nourishments from the roots.
