Study Notes
Taxonomy and Classification of Organisms
- Classification system includes levels: Kingdom, Phylum, Class, Order, Family, Genus, Species.
- Genus represents the most specific classification in the system.
Scientific Naming
- Scientific naming (binomial nomenclature) reduces confusion from different common names.
- Genus name is capitalized; species name is lowercase and italicized (e.g., Panthera leo).
Examples of Scientific Names
- African lion: Panthera leo
- Orange-barred sulfur: Phoebis philea
- Morpho rhetenor: Genus name is Morpho.
Taxonomic Relationships
- Panthera genus includes lions (Panthera leo), leopards (Panthera pardus), and tigers (Panthera tigris).
- All share the Genus 'Panthera'.
Domains and Kingdoms
- Eukarya domain consists of four kingdoms: Protists, Fungi, Plants, Animals.
- Prokaryotes are classified into two domains: Archaea and Bacteria.
- Eubacteria consist of unicellular prokaryotes, whereas Fungi, Plants, and Protists consist of eukaryotic cells.
Characteristics of Organisms
- Organisms with cell walls can be ruled out as Animalia.
- Fungi are heterotrophs that obtain energy from decomposing matter; they have chitin in their cell walls.
- Plants are multicellular autotrophs with cellulose in cell walls.
- Animals are multicellular heterotrophs with no cell wall.
Definitions and Concepts
- Taxonomy is the science of naming and grouping organisms.
- Genus includes organisms that are related and share certain characteristics.
- Species consists of groups of capable reproducing populations isolated from other groups.
- Phylum is ranked above Class and below Kingdom in taxonomy.
- Class is ranked above Order and below Phylum.
Identification Tools
- Dichotomous keys help in identifying organisms systematically, based on either/or choices (e.g., male or female).
