Study Notes

Taxonomy and Classification

Taxonomy is the scientific discipline focused on classifying organisms and understanding their relationships.
Binomial nomenclature is a standardized system for naming species, consisting of two names: the genus and the specific epithet.

Taxonomic Ranks

Genus ranks above species and below family, represented by a capitalized Latin name (e.g., Leo for lions).
A taxon is any taxonomic group, regardless of rank, such as species, family, or class.
Family fits between genus and order in the classification hierarchy.
Order is an important rank in taxonomy, situated between class and family; it can have superorder (above) and suborder (below) divisions.
Class is a taxonomic rank representational of organisms intermediate between phylum and order.
Phylum is a major taxonomic category, ranking below kingdom and above class.

Higher Taxonomic Categories

Kingdom is a high-ranking category that groups together all forms of life with common characteristics; examples include Animalia for animals and Plantae for plants.
Domain represents the broadest classification in the three-domain system established by Carl Woese, distinguishing life into Bacteria, Archaea, and Eukarya.

Major Groups of Life

Bacteria refer to microorganisms responsible for various infections, categorized under the domain Bacteria.
Eubacteria is the true bacteria group, characterized by its simple cells and rigid structures, contrasting with Archaea.
Archaea are distinct microorganisms that share similarities with bacteria but differ significantly in molecular structure, representing an ancient lineage.
Eukarya consists of eukaryotic organisms, which have cells with nuclei and membrane-bound organelles.
Protista, previously recognized as a kingdom, comprises unicellular eukaryotes that are now classified under Protoctista in modern systems.
Fungi includes a diverse group of spore-producing organisms like molds, yeast, and mushrooms, which feed on organic matter.
Plantae represents multicellular eukaryotes known as plants, including flowering plants and gymnosperms (e.g., conifers).
Animalia encapsulates all animals, from simple sponges to complex organisms like humans, forming one of the primary kingdoms of life.
