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.
