Study Notes
Taxonomic Classification of Organisms
- Eubacteria: Unicellular prokaryotic kingdom with cell walls containing peptidoglycan.
- Bacteria: Domain for unicellular prokaryotes characterized by peptidoglycan in their cell walls.
Domains of Life
- Eukarya: Domain that includes all organisms with nucleated cells, encompassing protists, plants, fungi, and animals.
Kingdoms in Eukarya
- Protista: Kingdom consisting of eukaryotic organisms not classified as plants, animals, or fungi, often unicellular or simple multicellular.
- Animalia: Kingdom of multicellular eukaryotic organisms that are heterotrophic (cannot produce their own food) and lack cell walls.
Taxonomic Hierarchy
- Kingdom: Large taxonomic group grouping closely related phyla.
- Phylum: Taxonomic category consisting of closely related classes.
- Class: Group of organisms that share similar traits and characteristics within an order.
- Order: Category grouping similar families based on shared characteristics.
- Family: Group of genera that exhibit common traits and characteristics.
Domain Characteristics
- Domain: The most inclusive category in the classification hierarchy, which is larger than a kingdom.
