Study Notes
Archaebacteria
- Kingdom of prokaryotic, single-celled organisms thriving in extreme environments.
- Autotrophs, including Halophiles (salt), Thermophiles (heat), and Methanogens (methane producers).
Eubacteria
- Kingdom mostly comprising free-living, prokaryotic bacteria across diverse environments.
- Heterotrophs or autotrophs, examples include E. coli, Salmonella, and blue green algae.
Protista
- Kingdom of eukaryotic organisms, either single-celled or simple multicellular.
- Includes heterotrophs and autotrophs like slime molds and Euglena, and encompasses organisms not classified as plants, animals, or fungi.
Fungi
- Kingdom of multicellular, eukaryotic organisms that decompose organic materials for nutrients.
- Heterotrophs including molds, yeast, rusts, and mushrooms, functioning as important decomposers.
Plantae
- Kingdom containing complex, multicellular organisms capable of photosynthesis.
- Eukaryotes with cell walls made of cellulose, examples include ferns and palm trees.
Animalia
- Kingdom of complex, multicellular organisms without cell walls, typically mobile with nervous systems.
- All animals, such as elephants, fall under this classification as heterotrophs.
Eukaryotic Kingdoms
- Animalia, Fungi, Plantae, and Protista are classified as eukaryotes.
Prokaryotic Kingdoms
- Archaebacteria and Eubacteria are classified as prokaryotes.
Classification Relationships
- Organisms in the same genus belong to the same family due to broader structural classification.
- Classification hierarchy: Kingdom, Phylum, Class, Order, Family, Genus, Species.
Evolutionary Relationships
- Classification levels indicate evolutionary links, starting with broad kingdoms and narrowing down to specific species.
Common Characteristics
- All six kingdoms share the presence of cells and consist of living organisms.
Species Estimates
- Scientific estimates suggest a range of 5 million to 100 million species exist on Earth, with only about 2 million identified.
