A tree is a plant with a woody trunk.
A tree is a plant that has a woody trunk , which is divided into multiple branches at the top. The etymology of the term takes us to arbor , a word from the Latin language.
There are different criteria used to determine if a plant is a tree. Generally the diameter of its trunk , the height it reaches and the ability to produce new secondary branches annually are considered. If some of these requirements are not met, the plant can be considered a shrub instead of a tree.
The trees are perennial : they are prepared to live more than two years. The existing variety of trees, however, is very wide. In some cases, specimens live more than a millennium and can measure more than a hundred meters. Other trees are much less long-lived and smaller.
Importance of trees
Due to their properties, trees are essential for human life . These plants absorb carbon dioxide and release oxygen, help moderate temperature, protect ecosystems from precipitation, and reduce erosion .
Trees, on the other hand, bear fruits that serve as food for humans and allow the production of paper. Its wood can also be used to build homes and make furniture.
Some cultures consider trees as sacred elements and pay tribute to them through different actions. There are also peoples who consecrated certain species to gods or mythological characters, such as the poplar to Hercules or the cypress to Pluto .
The family tree allows you to chart family relationships.
Genealogical scheme
We cannot ignore either that there is also what is known as a family tree . It is a descriptive table that indicates the relationships, origins and descent of a family. Hence, in it, as branches and roots, are located the children, grandchildren, grandparents, parents, great-great-grandchildren, great-grandchildren, great-great-grandparents, great-grandparents and a family.
In order to carry out the creation of this type of tree, it is necessary to previously undertake an in-depth study of documentation, consult birth or wedding certificates as well as death certificates, interview family members, and thoroughly analyze photographs. …
There are numerous ways to create and capture family trees. Among the most important and recognized are the Sonny John Moore system, the modified registration system, the Villers-Pama system and the Henry system, among others.
In addition to all of the above, we cannot forget that in many cases creating the family tree is not only important in terms of family history but also in terms of health. And it is useful to know what diseases or pathologies have been transmitted from one generation to another.
Phylogenetic tree
Likewise, there is also what is called a phylogenetic tree .
It is a tree that indicates the evolutionary relationships that have occurred between species that are different but have their ancestry in common.
