UNIT IV:Classification Flashcards
The science of classifying organisms
Taxonomy
The science of classifying organisms ACCORDING TO THEIR NATURAL RELATIONSHIPS
Phylogeny/Systematics
He introduced the formal System of Classification with Two Kingdoms
Linnaeus
He introduced the formal System of Classification with Two Kingdoms
Linnaeus
Proposed that bacteria and fungi be placed in Plantae
Nägeli
Proposed Three Kingdom System; addition of Kingdom Protista
Haeckel
Six Kingdoms proposed by Woese and Fox
Archaebacteria, Eubacteria, Protista, Fungi, Plantae, Animalia
Common denominator of three Domains (Bacteria, Archaea, Eukaryotes)
Ribosomes and Plasma
Project aiming to identify and record every species of life on earth in the next 25 years
All Species Inventory
Domain that includes plants, animals, protists and Fungi
Eukarya/Eukaryotes
[Domain] Includes pathogenic and non-pathogenic prokaryotes; has peptidoglycan cell walls
Bacteria
[Domain] Prokaryotes that do not have peptidoglycan in their cell wall; often live in extreme environments
Archaea
Strict anaerobes that produce methane from CO2 ans Hydrogen
Methanogens
Microorganisms that require high Concentration of Salt for survival
Extreme Halophiles
Microorganisms that normally grows in extremely hot environment
Hyperthermophiles
Explain Endosymbiotic Theory
Eukaryotic cells evolved from Prokaryotic Cells living inside one another as endosymbionts
Form of Classification established by Linnaeus
Taxonomic Hierarchy/ Hierarchical system of Classification
A level of grouping in the Taxonomic Hierarchy
Taxon/ Taxa
Method in which organisms are grouped based purely on inferred evolutionary relatedness, ignoring morphological similarity
Phylogenetic Taxonomy
A population of closely related interbreeding individuals
Species
A Group of genetically related species
Genus/Genera
Genera with Similar traits
Family
Families with Common Characteristics
Order/s
Orders with similar characteristics
Classes
Related classes
Phylum/Phyla
Related Phylas
Kingdom
Highest/Most Inclusive level in the Taxonomic Hierarchy
Domain
A population of cells with similar characteristics
Prokaryotic Species
Standard reference on bacterial classification
