Study Notes

Classification of Living Things

  • Living organisms are categorized using a hierarchical system starting with Domains and continuing down to individual species.
  • Three Domains include Eukarya (organisms with eukaryotic cells), Archaea (prokaryotes that often live in extreme environments), and Bacteria (common prokaryotes).

Levels of Classification

  • Six Kingdoms recognized:
    • Animalia: Multicellular eukaryotes that are heterotrophic and primarily reproduce sexually (e.g., Humans, Insects).
    • Plantae: Multicellular eukaryotes that autotrophically produce their food; reproduce sexually and asexually (e.g., Trees, Flowers).
    • Protista: Can be unicellular or multicellular; can be heterotrophs or autotrophs and reproduce via sexual and asexual methods (e.g., Euglena, Amoeba).
    • Fungi: Multicellular (some unicellular) eukaryotes that are heterotrophic, reproducing both sexually and asexually (e.g., Mushrooms, Yeast).
    • Archaebacteria: Unicellular prokaryotes, often found in extreme environments, can be heterotrophs or autotrophs, reproducing asexually (e.g., organisms in Hot Springs).
    • Eubacteria: Unicellular prokaryotes that encompass a variety of nutrient modes, reproducing asexually (e.g., Strep Throat causing bacteria).

Cell Types and Structures

  • Animalia and Plantae are both eukaryotes with complex cellular structures.
  • Fungi and Protista may exhibit unicellular or multicellular formations, influencing their modes of nutrition and reproduction.
  • Both Archaebacteria and Eubacteria are simpler prokaryotes, lacking a true nucleus.

Levels of Biological Organization

  • Biological hierarchy includes cells, tissues, organs, organ systems, organisms, populations, communities, ecosystems, and the biosphere.

Key Figure in Taxonomy

  • Carolus Linnaeus is termed the "Father of Taxonomy" for establishing the binomial nomenclature system, which categorizes organisms using two names.

Integumentary System Functions

  • Composed of skin, hair, and nails, serving critical protective roles.
  • Key functions include:
    • Acting as a barrier against infection and injury.
    • Regulating body temperature through sweat.
    • Removing waste products from the body.
    • Providing protection from UV radiation.
    • Serving as a major sense organ.
