Study Notes
Biology Branches
- Deals with the study of organisms, covering aspects such as Morphology, Anatomy, Classification, Taxonomy, Physiology, Ecology, and Production.
- Divided into three main branches: Zoology (study of animals), Phytology (study of plants), and Microbiology (study of microorganisms).
Organisms and Viruses
- Living organisms are divided into six kingdoms, excluding viruses.
- Viruses are very small, ranging from 30-300Nm in diameter, and are not classified into any kingdoms due to their ambiguous nature, sometimes resembling living and sometimes inanimate objects.
Kingdoms of Organisms
- Prokaryotic kingdoms:
- Archaebacteria
- Eubacteria
- Eukaryotic kingdoms:
- Protista
- Fungi (mycota)
- Animalia
- Plantae
Classification and Taxonomy
- Hierarchical ranking system:
- Kingdom
- Division
- Class
- Order
- Family
- Genus
- Species
- Scientific nomenclature system:
- Binary system, where every living being is given a unique two-part name.
- Genus name starts with a capital letter.
- Species name starts with a small letter.
- Examples: Rosa galli, Zea maiz
