Purpose Of A Lab On Systematics And Taxonomy

You can identify a eukaryotic cell by its encased nucleus, containing the majority of its DNA and organelles surrounded by a membrane. Plant and Animal cells have double membranes and a housed nucleus therefore they are eukaryotic cells; organisms which do not contain a double membrane and an encased nucleus are known as prokaryotes, e.g. bacteria. The eukaryotic cell is made up of many membrane bound organelles which all have a specific function.

One reason why branch of taxonomy is important for future scientific knowledge is because science is able to distinguish the difference between species. Being able to do distinguish the difference between

Phylogenetic species concept would be the most expedient and effective process of collecting, naming, and describing what she found. Phylogenetic relies on common ancestry and shared evolutionary when defining a species.

There are three domains of organisms, which are Bacteria, Archaea, and Eukarya. Domain Bacteria and Domain Archaea prokaryotes, and Domain Eukarya inevitably includes eukaryotes. Prokaryotes are the most abundant and able to adapt to many different environments. They do not contain a nucleus, circular DNA,

The purpose of taxonomy is to describe and classify the different types of organisms that roam the continents into groups Genus and species. In biology it’s used to classify organism using latin names and to narrow down 1 organism from Kingdom to species.

A species is certain kind of animal, plant, fungus or other organism. Which is a group of individual that are part of interbreed in nature, it is the largest gene pool under a natural condition. It is when a pair of organisms produce and offspring in nature and both parents need to belong to same species. This definition does not include many types of bacteria which are capable to asexual reproduction. Another difficult way of understanding would be like for example a cat species are capable of hybridizing such as a lion and a tiger who mate and produce a liger as well as a cross between a male jaguar and female lion which produce a jaglion. Species are formed through a process called speciation and this happens when lineage of single splits into to two or more separate species, this is how new species are created.

In the Linnaean classification system, all organisms are placed in a ranked hierarchy.   His system was one of small groups building into larger ones. The current groupings of organisms from largest to smallest are kingdom, phylum, class, order, family, genus, and species

Domain eukarya- All organisms grouped within the domain eukarya are also considered single celled. Eukaryotic cells are specifically grouped by the things each organism lives off, or by the things they eat individually.

Species are groups of organisms that share characteristics or have some characteristics that are similar and can successfully interbreed. Species can also be broken down more to include subspecies.

It is the same method that Linnaeus used to make an inventory of living organisms; by defining characteristics, classifying and grouping.

The distinction was made from Prokaryotes Bacteria and Archaea which are classified different to the domain of the Eukaryotes and there four kingdoms (animals, plants, protists and fungi). The Prokaryotes meaning comes for the Greek word meaning (pro) “before” and (karyon) meaning “nut or kernel” Most of the prokaryotes can be seen as a unicellular organisms although the myxobacteria have been seen in different stages in their life cycles like in colonies of cyanobacteria. (Also call blue green algae) Which are predominantly photosynthetic and also fall into prokaryotes Eubacteria kingdom. Although you can find some Algae as Eukaryotes domain. Like most algae’s that are photosynthetic can produce oxygen gas as a by-product. Theorists have proposed that this could have been the link to change the early atmosphere on earth into and oxidizing one that enabled the stimulation of the biodiversity of life that we see today.

It is evidently known that the cell is the basic unit of life. Cells are microscopic, membrane-bound units which contain biomolecules allowing them to carry out functions, sustain life and self-replicate. Although every living cell comes under one of the 6 kingdoms in the biological taxonomy of living organisms, the two most distinct types of cells are eukaryotic cells and prokaryotic cells. Prokaryotes (pre-nucleus) are single-celled organisms which do not contain a nucleus nor do they have any membrane-bound organelles within them. Eukaryotes (literally meaning “true nucleus”) were developed many years after prokaryotes and can either be single-celled or multi-cellular organisms.

. Bacteria and Archaea are split into separate domains because bacteria include all pathogenic prokaryotes, as well as nonpathogenic prokaryotes that are found in soil and H2O. What are also found in this domain are photoautotrophic prokaryotes. Archaea includes prokaryotes that do not have peptidoglycan in their cell walls. Prokaryotes are mostly related to eukaryotes than they are to different prokaryotes. This is when they were split into two domains.

Animals share certain characteristics such as being heterotrophs, multicellular, no presence of cell walls, and many more. Animals can further be divided through the use of a phylogeny, which is an evolutionary tree. A phylogeny shows patterns of relationships between several different types of species. When branching off to dissimilar species, characteristics are taken accounted for whether they are derived, ancestral, or shared traits. Traits include symmetry, tissues, segmentation, body cavities, and patterns that deal with the development of embryos.

Taxonomy is a section of science which puts organisms into biological groups and names them, based on their characteristic features. The history of this science started when ancient Greek and Roman scientists classified certain animal and plant species known to them. Since that time, the way of classifying organisms has changed several times, as the ways of gathering information about the species improved. Scientists of different times proposed their own
