Biology Classification Quiz

Classification and Taxonomy

• The largest group of organisms is the Kingdom, which encompasses numerous species.
• Scientific names of organisms are determined by their Genus and species classifications.
• The modern classification system was developed by Carl Linnaeus.
• The field of classifying and naming living organisms is known as Taxonomy.

Kingdoms and Organism Characteristics

• Archaebacteria contains extremophiles, organisms that thrive in extreme environments.
• Organisms in the kingdom Animalia are classified as multicellular and heterotrophic, meaning they cannot produce their own food.
• The six kingdoms of life include Archaebacteria, Eubacteria, Protista, Fungi, Plantae, and Animalia.

Domains and Classification Levels

• There are three domains of life: Archaea, Bacteria, and Eukarya.
• The eight levels of biological classification, from smallest to largest, are: Species, Genus, Family, Order, Class, Phylum, Kingdom, Domain.

Autotrophic and Unicellular Organisms

• The Protista kingdom includes unicellular autotrophic organisms, capable of photosynthesis.
• Plants and animals are both classified as eukaryotic organisms, sharing complex cellular structures.

Scientific Naming and Relationships

• The scientific classification system is referred to as Binomial nomenclature, which assigns two names (Genus and species) to each organism.
• Canis lupus refers to the wolf, with "lupus" being the species name.
• Cladograms are diagrams used to illustrate the relationships between various organisms based on their evolutionary history.

Classifications and Relationships

• If two organisms belong to the same phylum, they must also share the same kingdom classification.
