Study Notes
Taxonomy and Classification
- Class: A taxonomic category containing similar orders; ranks between order and division (plants) or order and phylum (animals).
- Classification: Systematic grouping to distinguish and identify organisms based on shared characteristics.
- Division: In plant classification, a level that groups similar classes; ranks between kingdom and class.
Major Taxonomic Categories
- Domain: The largest taxonomic category, encompassing all forms of life.
- Kingdom: A major grouping that includes similar phyla; ranks between domain and phylum.
- Phylum: Groups of similar classes; ranks between kingdom and class.
Hierarchical Structure of Classification
- Order: Contains similar families, positioned between class and family.
- Family: Groups of similar genera; falls between order and genus.
- Genus: A category for similar species; ranks between family and species, also the first part of a scientific name.
The Smallest Taxonomic Category
- Species: The smallest grouping, including only similar varieties, and the second part of a scientific name.
Taxonomy Terms
- Taxon: Taxonomic categories used in classification (plural: taxa).
- Taxonomist: A scientist specializing in classifying organisms.
- Taxonomy: The scientific discipline focused on classifying organisms.
Classification Systems
- Continuous hierarchy in plant classification:
- Kingdom > Division > Class > Subclass > Order > Family > Genus > Species.
- Dichotomous Key: A tool used in taxonomy with two-choice questions for identifying species and taxa.
Evolutionary Relationships
- Systematics: The study of organisms based on evolutionary relationships.
Microorganism Classification
- Archaea: Prokaryotic organisms (archaeobacteria) distinct in structure from bacteria, capable of living in extreme environments.
- Eubacteria: A group of prokaryotic organisms, including typical bacteria and cyanobacteria.
- Prokaryote: Cells without membrane-bound nuclei.
- Eukaryote: Cells with membrane-bound nuclei and organelles.
Biological Characteristics
- Morphology: The physical form and structure of an organism, vital in species definition.
- Reproductive Isolation: Barrier separating populations, hindering species from reproducing, leading to genetic variations and new species development.
