Study Notes
Domains of Life
- Three domains: Bacteria, Archaea, and Eukarya.
- Bacteria and Archaea consist of prokaryotic cells; Eukarya contains eukaryotic cells.
Kingdoms of Life
- Six kingdoms: Eubacteria, Archaebacteria, Protista, Plantae, Animalia, and Fungi.
Taxonomy Classification
- Eight levels of classification in order: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Mnemonic for classification: "Did King Philip Come Over For Great Spaghetti?"
Classification Definition
- Organisms are classified based on physical characteristics and genetic relationships.
Taxonomy
- Sub-discipline of biology focused on identifying, naming, and classifying organisms.
Morphology
- Study of the form and structure of organisms.
Scientific Naming (Bionomial Nomenclature)
- Scientific names consist of two parts: genus and species.
- Naming rules: italicize or underline the entire name, capitalize the genus name, and use a lowercase letter for the species name.
Detailed Taxonomic Ranks
- Domain: Highest taxonomic rank above kingdom, includes Archaea, Bacteria, and Eukarya.
- Kingdom: Second highest rank, includes Animalia, Plantae, Fungi, Protista, Archaebacteria, and Eubacteria.
- Phylum: Classification above class and under kingdom.
- Class: Rank above order and under phylum.
- Order: Classification above family and under class.
- Family: Rank above genus and under order.
- Genus: Classification above species and under family.
- Species: Basic unit of classification below genus.
Domains Explained
- Archaea: Ancient prokaryotes, unicellular, related to kingdom Archaebacteria, often found in extreme environments.
- Bacteria: True bacteria, unicellular prokaryotes, associated with kingdom Eubacteria, forms the most common bacteria.
- Eukarya: Comprises all organisms with a nucleus including protists, plants, fungi, and animals.
Kingdoms Detailed
- Archaebacteria: Unicellular prokaryotes, some produce methane, thrive in extreme conditions such as high temperature and pressure.
- Eubacteria: Unicellular prokaryotes, encompasses the majority of bacteria found in various environments.
- Protista: Eukaryotic kingdom that includes unicellular and multicellular organisms that are neither plants, animals, nor fungi (e.g., Amoeba, Euglena).
- Fungi: Multicellular organisms that decompose organic material to obtain nutrients (e.g., mold, mushrooms, yeast).
- Animalia: Complex, multicellular organisms lacking cell walls, which can move and respond to their environment (e.g., mammals, birds, insects).
- Plantae: Complex, multicellular organisms that photosynthesize using sunlight, characterized by green color and cellulose cell walls (e.g., ferns, flowering plants).
