Study Notes
Taxonomy and Classification
- Taxonomy is the science of grouping and naming organisms.
- Aristotle categorized organisms into two primary groups: plants and animals.
Scientific Naming
- The scientific name for humans is Homo sapiens, where "Homo" is the genus name and "sapiens" is the species name.
Domains and Kingdoms
- There are three domains of life: Bacteria, Archaea, and Eukarya.
- Six kingdoms of organisms include:
- Bacteria
- Archaea
- Protista
- Fungi
- Plantae
- Animalia
Characteristics of Kingdoms
- The Animalia kingdom is unique as its organisms lack cell walls.
- The Plantae kingdom is characterized by multicellular organisms that have cell walls made of cellulose and are autotrophic.
- Both the Bacteria and Archaea kingdoms consist of organisms with prokaryotic cells.
- The Fungi kingdom includes eukaryotic organisms with cell walls made of chitin, commonly parasitic in nature.
- Organisms in the Bacteria kingdom possess prokaryotic cells, are anaerobic, and have cell walls of peptidoglycan.
- The Protista kingdom contains diverse eukaryotic organisms, including algae, kelp, mold, mildew, and amoebas.
- The Plantae kingdom includes autotrophic, multicellular, photosynthetic organisms that have specialized structures like roots, stems, and leaves.
Levels of Biological Organization
- Levels of organization in taxonomy are classified as follows: kingdom, phylum, class, order, family, genus, and species.
Viruses
- Viruses contain DNA or RNA as genetic material but do not have cellular structure.
- Viruses require a host to reproduce.
Anatomy of Animal Kingdom
- Only the Animalia kingdom contains organisms with higher-level organization into tissues, organs, and systems.
