Taxonomy is the study and description of the variation of organisms, the investigation of the causes and consequences of this variation, and the manipulation of the data obtained to produce a system of classification. Through the use of an evolutionary tree I will be able to represent the relationships present in ten different organisms from the Monera, Protista, and Plant Kingdoms. I hope to accomplish a proof that a flowering plant evolved from an oscillatria. The evolutionary tree will consist of branches and nodes. A branch represents a single line of decent from a common ancestor and a node represents a time of genetic divergence and speciation. The tree will be composed of morphological, physiological, and behavioral traits. We will use a list of ten operational taxonomic units and present 15 attributes. The attributes must be different in order to see the differences between species. The tree should contain a species that will be the outgroup
. The outgroup cannot hold any of the attributes that are going to be investigated. After the organisms and attributes are chosen and compared an evolutionary tree can be created.
After examining the evolutionary tree the spirogyra comes next and is the first multicellular organism in this tree to sexually reproduce. The spirogyra is a green algae found in water and logically comes after the chlamydoma because it is producing its own food and reproducing sexually. The spirogyra gave rise to a new species known as the chara. The concrete evidence that the land plant evolved from the microscopic organisms like the paramecium. The chara is the first organism to possess the attribute of branching. It also reproduces sexually on its leaves. This organism can only move to evolve and become one of the first land “plants” known as moss, bryophytes. These “plants” are the first to display rhizoids or roots in order to live on land. This species
