Study Notes
Classification System
- A method for organizing and categorizing organisms based on similarities into taxa.
Binomial Nomenclature
- Developed by Carolus Linnaeus; assigns each species a two-part scientific name.
Scientific Name
- Composed of two parts: genus and species, representing the taxonomic designation of an organism.
Domains of Life
- Domain: Highest classification level; includes Archaea, Bacteria, Eukaryotes.
- Domain Bacteria: Encompasses Kingdom Eubacteria, characterized by peptidoglycan cell walls.
- Domain Archaea: Includes Kingdom Archeabacteria, consisting of prokaryotes in extreme environments; lacks peptidoglycan.
- Domain Eukarya: Contains Kingdoms Protista, Fungi, Plantae, and Animalia; all are eukaryotes.
Kingdom Classification
- Kingdom Eubacteria: Contains free-living prokaryotic organisms, classified under Domain Bacteria.
- Kingdom Archeabacteria: Comprises prokaryotes found in extreme environments, classified under Domain Archaea.
- Kingdom Animalia: Multicellular eukaryotes that are motile and lack cell walls, classified under Domain Eukarya.
- Kingdom Plantae: Multicellular eukaryotes with cellulose-containing cell walls, classified under Domain Eukarya.
- Kingdom Fungi: Multicellular eukaryotes with chitin in their cell walls, includes mushrooms and molds, classified under Domain Eukarya.
- Kingdom Protista: Includes various unicellular and multicellular eukaryotic organisms, such as amoeba and algae, classified under Domain Eukarya.
Organism Types
- Heterotroph: Organisms that derive energy from consuming other organisms.
- Autotroph: Organisms capable of producing their own energy through processes like photosynthesis.
- Prokaryote: Cells that lack a nucleus.
- Eukaryote: Cells that contain a nucleus.
- Unicellular: Organisms made up of a single cell.
- Multicellular: Organisms composed of two or more cells.
Taxonomic Hierarchy
- Node: Represents a point of a common ancestor within a phylogenetic tree.
- Derived Characteristic: Traits gained over time that were not present in previous forms.
- Clade: A group of organisms derived from a common ancestor.
- Taxonomy: A scientific branch focused on describing, identifying, naming, and classifying organisms.
- Cladogram: Diagram illustrating the branching evolution of species from common ancestors.
Key Contributions
- Carolus Linnaeus: Established the foundation for modern classification; recognized as the "Father of Taxonomy."
- Taxon: An organizational level or group into which organisms are classified.
