Study Notes
- Viruses are nonliving and are classified by their genetic material; they require a host cell.
Taxonomy
- "Taxis", a Greek word, means "put in order"
- Taxonomy is the grouping and assigning of organisms with a specific name.
Fathers of Taxonomy and Binomial Nomenclature
- Carolus Linnaeus is the father of taxonomy and is credited with binomial nomenclature.
Human classification
- Human Classification progresses from Kingdom to Species: Animalia, Chordata, Mammalia, Primates, Hominidae, Homo, and Sapiens.
Earthworm classification
- Earthworm Classification progresses from Kingdom to Species: Animalia, Annelida, Clitellata, Opisthopora, Limbricidae, Lumbricus, and terrestris.
Binomial Nomenclature
- Binomial nomenclature is a two-word naming system
- The genus name is a noun, usually plural, and must be underlined or italicized.
- Genus names cannot be written or typed in lowercase letters.
Classification
- "Domain" is a broad level added to the classification system based on cell type; it is more inclusive than Kingdom.
- The Kingdom "Monera", which once included archaebacteria and eubacteria, no longer exists.
Etymology
- The English word "virus" is derived from a Latin word that means "poison."
- “Chordata” means having a backbone
- “Homo sapien” means wise man
Archaebacteria and Eubacteria
- Archaebacteria can be classified as methanogens, halophiles, and thermoacidophiles; they live in very extreme environments.
- Eubacteria live in hospitable places.
Bacteria
- Bacteria can be classified based on shape
- Cocci are spherical-shaped
- Bacilli are rod-shaped
- Bacteria reproduce asexually by binary fission and sexually by conjugation.
- Bacteria can reproduce in about 20 minutes.
- Bacteria are obligate aerobes.
Viruses
- The shape of the capsid layer in a virus is determined by proteins
- Viral cycles can be lytic or lysogenic, active or inactive.
Species
- The Species name is descriptive, usually an adjective, and is written/typed in lowercase.
- Species names must be underlined or italicized.
