Study Notes
Taxonomy Overview
- Taxonomy is the science of naming and classifying organisms based on structural comparisons and genetic evidence.
- There are 8 levels of taxonomy, starting from Domain down to Species.
Taxonomic Categories
- Domain is the largest taxonomic category, including Archaea, Bacteria, and Eukarya.
- The six kingdoms of life include: Eubacteria, Archaebacteria, Protista, Fungi, Plantae, and Animalia.
Kingdom Animalia
- Composed of multicellular, eukaryotic organisms that are heterotrophic and lack a cell wall.
- Includes a diverse range of species from insects to elephants, classified into vertebrates and invertebrates.
Kingdom Plantae
- Multicellular and eukaryotic, Plantae are autotrophic organisms with a cell wall made of cellulose.
- Plant species exhibit a vast range in size, from 1 mm to 115 m.
Kingdom Fungi
- Includes unicellular or multicellular, eukaryotic organisms that are heterotrophic and have a cell wall made of chitin.
- Comprises important decomposers such as mushrooms, yeasts, and molds.
Kingdom Protista
- Primarily unicellular and eukaryotic, Protista consists of organisms that do not fit into other eukaryotic kingdoms.
- Organisms may or may not possess cell walls and can be either autotrophic or heterotrophic.
Kingdom Archaebacteria
- Archaebacteria are unicellular, prokaryotic organisms that possess cell walls.
- They can be autotrophic or heterotrophic, with many living in extreme environments.
Kingdom Eubacteria
- Eubacteria are unicellular and prokaryotic, characterized by cell walls containing peptidoglycan.
- They can be autotrophic or heterotrophic, with some species capable of photosynthesis, while others are disease-causing or decomposers.
Summary of Biological Domains
- Bacteria: Eubacteria
- Archaea: Archaebacteria
- Eukarya: Comprises Animalia, Plantae, Protista, and Fungi.
Kingdom Characteristics
- Body type can be unicellular or multicellular.
- Organisms may be prokaryotic or eukaryotic based on cell type.
- Most kingdoms have distinct cell wall structures.
- Nutritional modes include autotrophic or heterotrophic.
