Study Notes
Prokaryotes and Eukaryotes
- Prokaryotes lack membrane-bound organelles and a nucleus, containing only DNA.
- Eukaryotes possess membrane-bound organelles, a nucleus, and DNA.
Cellular Organization
- Unicellular organisms consist of a single cell.
- Multicellular organisms are composed of multiple cells.
Nutritional Modes
- Autotrophic organisms can synthesize their own food.
- Heterotrophic organisms are unable to produce their own food.
Types of Organisms
- Bacteria are unicellular and classified as prokaryotes.
- Archaebacteria are also prokaryotes, often intolerant to oxygen, and include many extremophiles.
- Protists are primarily eukaryotic; most are unicellular, but some can be multicellular.
- Fungi are heterotrophic, often unicellular or multicellular, and generally possess cell walls.
- Plantae are autotrophic and predominantly multicellular organisms.
- Animalia primarily consists of multicellular, heterotrophic organisms.
Taxonomic Classification
- Taxonomic levels, arranged from broad to specific, include Domain, Kingdom, Phylum, Class, Order, Family, Genus, and Species.
Scientific Naming
- A scientific name combines an organism's Genus and Species, like Panthera Leo for lions.
- Scientific names provide a universal language for scientists, eliminating regional language barriers.
Classification System Evolution
- The classification system adapts based on advancements in DNA and cell structure knowledge.
- Discoveries of new organisms and ongoing evolutionary changes contribute to potential updates in classification.
