As the saying goes, "How high a tree is, how deep its roots are." This statement has a certain basis and confirmation, because the more developed and deeper the roots of trees are, the more lush the branches and leaves on the general surface will be. According to this truth, the roots can penetrate into the ground for tens of meters or even deeper. Different tree species have different root lengths, including shallow roots and deep roots. The plant with the deepest roots in the world is in the echo cave near Oristad, South Africa. There is a fig tree there. It is estimated that its roots are 12 meters deep underground. If it is hung in the air, it is as high as 4 stories. This is the deepest root.

When it comes to trees, many people only pay attention to their height or volume, or their appearance and vitality. Few people pay attention to the tree's own ability, such as the inside of the tree, how much water they can store. In fact, few people pay attention to this kind of tree, but it is not without it. If no one really cares, I believe this is the root of the tree. To sum up in one sentence, we humans only pay attention to the outside of the tree, but we don't pay attention to the inner beauty of the tree.

As an important part of a tree, roots play a great role in the survival probability of a plant. A tree with thick and deep roots can have a higher survival probability. On the contrary, the shallower and thinner the roots, the more difficult it is to survive. Take plants with strong water storage capacity, you can observe how long their roots are. For example, as a long-lived plant-Celastrus japonicus, it has been able to survive in the desert for thousands of years because of great contributions.
