It is the scientific study of the diversity of organisms and their evolutionary relationships and an important aspect of systematics is taxonomy. 

It is a dynamic science as it involves constant reevaluation of data, hypotheses, and theoretical constructs. As new data are discovered and old data are subjected to reinterpretation, the ideas change.

It can help us understand evolutionary patterns that can provide information to the origin and spread of beneficial and harmful varieties.

It is also useful in predicting characteristics of newly discovered species.

New species can be classified based on specific characters that it shares with other organisms in a particular grouping so as to record biodiversity.

Biological knowledge can be communicated efficiently among scientists.

It is the science of classification and it involves the naming of organisms (nomenclature).

He created the hierarchical classification system using seven taxonomic categories.

In hierarchical classification system, each successive level of classification becomes more and more specific.

Which of the following is the highest taxonomic rank?

Which of the following is the second taxonomic rank?

Which of the following is the third taxonomic rank?

Which of the following is the fourth taxonomic rank?

Which of the following is the fifth taxonomic rank?

Which of the following is the sixth taxonomic rank?

Which of the following is the seventh taxonomic rank?

Which of the following is the eight taxonomic rank?

It is the highest taxonomic rank in the hierarchical biological classification system, above the kingdom level.

There are three part, the Archaea (salt and heat-loving microbes), the Eubacteria (carbon-eating bacteria), and the Eucarya (anything that don’t belong from the two).

It is the second highest taxonomic rank, just below domain. 

It is divided into smaller groups called phyls.

It is a level of classification or taxonomic rank below kingdom and above class.

Traditionally, in botany, the term division has been used instead of phylum, although the International Code of Nomenclature for algae, fungi, and plants accepts the terms as equivalent.

This category includes related orders.

For example, in this taxonomic rank includes monkey, gorilla, and gibbon is place in class Mammalia along with order Carnivora that includes animals like tiger, cat, and dog.

It is a taxonomic rank that is used in classifying  organism.

Generally below the class, and compromised of families sharing s set of similar nature of character.

The similar characters are less in number as compared to different genera included in a family.

It is a taxonomic rank in the classifications of organisms between genus and order.

It has a group of related genera with still less number of similarities as compared to genus and species

It comprises a group of related species which has more characters in common in comparison to species of other genera.

It aggregates of closely related species.

It is a taxonomic rank that studies consider a group of individual organisms with fundamental similarities as a species.

One should be able to distinguish one species from the other closely related species based on distinct morphological differences.

It is an arrangement of organisms into groups on the basis of their similarities. 

The grouping is done from less inclusive to more inclusive group until the organisms are assembled into a final most inclusive group.

The sequence of classification follows a fixed system of hierarchy of categories such as species-genus- family -order and so on. 

The classification process includes assigning appropriate position and rank to a new taxon. 

It involves arranging organisms into groups based on their similarities, which reflect evolutionary relationships among lineages.

This classification system is based upon one or a few easily observable characteristics.

It places organisms into groups for purposes of convenience and economy.

Organisms can be placed into groups according to their color, how they move, habitat or their size.

This taxonomic system was introduced by Jean Bauhin in 1623.

Generally, this classification is based on many features, internal as well as external and considers information from many branches of biology such as anatomy, biochemical, physiological, morphology, embryology, and cytology.

It is based on as many phenotypic similarities (similarities in appearance) as possible.

Hence, the more similarities there are between two organisms, the more likely these two organisms belong to the same group.

This is a quantitative approach.

In this approach, computer programs are used to analyze data and group organisms according to the number of shared characteristics. 

This involves Bioinformatics (branch of biology involving the application of computers and computer science to the understanding and modeling of the structures and processes of life.

 This classification involves grouping organisms based on shared characteristics which reflect evolutionary relationships or phylogeny. 

This strategy is called evolutionary classification.

Biologists now group organisms into categories that represent lines of evolutionary descent or phylogeny and not just physical similarities.

When biologists compare similarities, they now consider structural, physiological, development, behavioral and molecular traits. They look for homology in different organisms.

It is a family tree based upon this type of classification.

It is on of the tools used to classify organisms in this classification system.

It is used to trace the process of evolution in a group of organisms based on shared derived characteristics.

Its represents a common ancestor for all the taxa.

Each branch point (referred to as a node) represents the most recent common ancestor. The node also represents a divergence or splitting of two or more new groups from a common ancestor.

A tool used to identify and name unfamiliar organism.

Involves characteristics for a specific taxon.

Usually, the characteristics are observable.

It is composed of statements called leads.

The two characteristics must be contrasting.

The leads must lead to a new lead up to the smallest classification.

It is the formal system of naming species of living things.

According to this system, each organism is known my two names – the genus name and the species name. 

In Binomial nomenclature, the names are all written in Greek.

In Binomial nomenclature, the name of the genus always begins with a capital letter.

In Binomial nomenclature, the species name also begins with a capital letter.

In Binomial nomenclature, the scientific names are always bolded. 

When handwritten, the genus name and species name have to be underlined

Advantages:

- Makes the classification simple and easy.

- Less time consuming and manage to classify with little information of one or two characters only.

- Poorly known species can be classified easily.

- Less instruments of classification are needed.

- Very specific to the character of choice.

Disadvantages:

- Not universally applicable.

- Cannot initiate bold prediction.

- Since the choice of characters are arbitrary, the exact correlation cannot be established.

- Various unrelated taxa, which are not at all related but, similar in one respect only, have been placed under the same Class.

- Cannot establish evolutionary relationships among taxa.

Advantages:

- Makes the classification more inclusive.

- It can be used for bold prediction of ranks and categories for newly identified species.

- Contains more exclusive information about the taxonomic hierarchy.

- It can help to predict properties of even not-so-closely related species.

- Members of different groups are mostly similar in hereditary pattern.

Disadvantages:

- The complexity level is more than artificial.

- Combursive and time consuming.

- Less known plants cannot be classified through this system since their characteristics are not fully defined.

- A single property of interest cannot be taken into consideration for classification.
