Study Notes
Systematics and Taxonomy
- Systematics is the study of biological diversity and the relationships among organisms.
- Taxonomy is the science of describing, naming, and classifying species.
- A taxonomist is a person who studies how to classify organisms.
Phylogenetics and Nomenclature
- Phylogenetics is the study of evolutionary relationships among species.
- A tautonym is a scientific name in which the same word is used for both genus and species.
- Different codes of nomenclature exist for different groups of organisms:
- Algae, Fungi, and Plants: International Code of Botanical Nomenclature (ICBN)
- Animals: International Code of Zoological Nomenclature (ICZN)
- Bacteria: International Code of Nomenclature Bacteria (ICNB)
- Viruses: International Committee on Taxonomy of Viruses (ICTV)
Plant Types
- Non-Vascular Plants are plants that lack a vascular system, specifically the xylem and phloem that transport nutrients and water to the plant.
- Vascular Plants are plants having a specialized system for carrying fluids that includes xylem and phloem.
Test your knowledge of systematics, taxonomy, and phylogenetics. Learn about the classification of organisms, including algae, fungi, and plants, and understand the International Codes of Nomenclature. Identify the relationships among species and their evolutionary history.
