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
