4.2.1 Taxonomy

• What is taxonomy defined as?

  Classifying and naming organisms
• The function of taxonomy called classification involves organizing organisms into groups based on shared characteristics
• The binomial nomenclature system assigns a universally accepted two-part name to each organism.
• Why is taxonomy considered crucial?

  Understanding biodiversity
• Match the taxonomic function with its description:

  Classification ↔️ Grouping organisms based on shared features

  Identification ↔️ Determining an organism's group

  Nomenclature ↔️ Assigning a unique two-part name
• Order the major levels of the taxonomic hierarchy from broadest to narrowest.

  1️⃣ Domain

  2️⃣ Kingdom

  3️⃣ Phylum

  4️⃣ Class

  5️⃣ Order

  6️⃣ Family

  7️⃣ Genus

  8️⃣ Species
• What is the broadest classification level in the taxonomic hierarchy?

  Domain
• A species is the narrowest classification level where organisms can interbreed and produce fertile offspring.
• Match the taxonomic level with its example:

  Domain ↔️ Bacteria

  Kingdom ↔️ Animalia

  Phylum ↔️ Chordata

  Genus ↔️ $Homo$

  Species ↔️ $Homo sapiens$
• The binomial nomenclature system uses two Latin names to identify an organism
• Which part of the binomial name is always capitalized?

  Genus
• Both the genus and species names in the binomial nomenclature system are either italicized or underlined.
• What is taxonomy defined as?

  Science of classifying organisms
• The third primary function of taxonomy is nomenclature
• What is an example of a classification group in taxonomy?

  Kingdom, Phylum
• The binomial nomenclature for humans is $Homo sapiens$.
• Arrange the levels of the taxonomic hierarchy from broadest to narrowest.

• Match the taxonomic level with its example.

  Domain ↔️ Bacteria

  Kingdom ↔️ Animalia

  Phylum ↔️ Chordata

  Genus ↔️ $Homo$

  Species ↔️ $Homo sapiens$
• The binomial nomenclature system uses two Latin names to classify organisms: genus and species
• In binomial nomenclature, both the genus and species names are italicized or underlined when written.
• What is the binomial name for human beings?

  $Homo sapiens$
• What does the genus name in binomial nomenclature represent?

  Groups closely related species
• Arrange the principles of classification in taxonomy based on their logical sequence.

  1️⃣ Shared Characteristics

  2️⃣ Evolutionary Relationships

  3️⃣ Hierarchical System

  4️⃣ Binomial Nomenclature
• Match the principle of classification with its description.

  Shared Characteristics ↔️ Grouping based on similar traits

  Evolutionary Relationships ↔️ Grouping according to common ancestors

  Hierarchical System ↔️ Organizing taxa from broad to narrow categories

  Binomial Nomenclature ↔️ Assigning unique two-part names to species
• Taxonomy helps in understanding biodiversity and evolutionary relationships.
• Why are standardized naming conventions important in taxonomy?

  Ensure clear communication
• What is an example of a species whose classification is used in resource management?

  $Pinus sylvestris$
