Study Notes
Classification and Taxonomy
- Classification: Grouping organisms based on similarities.
- Taxonomy: Scientific study focused on the classification of living things.
Key Figures in Taxonomy
- Carolus Linnaeus: Swedish botanist and zoologist known as the "father of modern taxonomy"; developed binomial nomenclature, naming organisms using a two-part Latin system.
Naming Organisms
- Binomial Nomenclature: Each organism receives a unique two-part name indicating its genus and species.
Classifications and Groups
- Genus: A group containing closely related organisms.
- Species: A group of similar organisms capable of breeding and producing fertile offspring.
- Levels of Classification: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
Tools and Concepts
- Taxonomic Keys: Tools that aid in identifying organisms.
Cell Types
- Prokaryotes: Unicellular organisms without a nucleus or membrane-bound organelles.
- Eukaryotes: Organisms with nucleated cells; includes protists, plants, animals, and fungi.
Domains of Life
- Domain Bacteria: Prokaryotic cells characterized by cell walls with peptidoglycan; can be autotrophs or heterotrophs.
- Domain Archaea: Genetically distinct single-celled prokaryotes, often found in extreme environments.
- Domain Eukarya: Comprises organisms with eukaryotic cells like protists, fungi, plants, and animals.
Kingdoms of Life
- Protist Kingdom: Mostly unicellular eukaryotes; can be heterotrophic or autotrophic with examples like algae and kelp.
- Fungi Kingdom: Eukaryotic organisms that lack chlorophyll; includes yeasts, molds, and mushrooms.
- Plant Kingdom: Multicellular, eukaryotic autotrophs capable of photosynthesis, typically green.
- Animal Kingdom: Diverse eukaryotic organisms with adaptations for food procurement and digestion.
Influential Theories
- Charles Darwin: Natural historian known for the theory of evolution by natural selection; authored "On the Origin of Species" and "The Descent of Man".
- Evolution: The gradual change in organisms over time from ancient ancestors.
Evolutionary Relationships
- Branching Tree Diagram: Illustrates evolutionary relationships between organisms, depicting the order in which characteristics evolved.
- Shared Derived Characteristics: Traits unique to specific species or groups due to common ancestry.
- Convergent Evolution: The phenomenon where unrelated organisms evolve similar traits.
