    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.
