Study Notes

Classification Process

Characterisation: Observe all organism traits such as exoskeleton type, appendages, and sensory structures like antennae.
Identification: Use documented traits to hypothesize the organism's classification. For instance, a chitinous exoskeleton and jointed appendages may indicate an insect.
Classification: Organisms are organized into hierarchical levels based on defined characteristics.
Nomenclature: Assign specific names to species only after determining classification.

Taxonomic Categories

Taxonomic Hierarchy: Refers to the organization of biological categories either from broadest to most specific or vice versa.
Main Taxonomic Categories:
- Kingdom: Highest classification level.
- Phylum: Next level, grouping organisms based on major body plans.
- Class: Further categorization within a phylum.
- Order: Groups families that share common characteristics.
- Family: Contains closely related genera.
- Genus: A group of species sharing common traits.
- Species: The most specific category, identifying individual organisms.
Mnemonic for Recall: "Keep [Kingdom] Podium [Phylum] Clean [Class] On [Order] Fam [Family] Get [Genus] Sick [Species]" aids memory of categories.
