Study Notes
Six Kingdoms of Life
- Living organisms are classified into six kingdoms: Plants, Animals, Protists, Fungi, Archaebacteria, and Eubacteria.
- Plants and some protists possess cell walls made of cellulose.
Three Domains
- Life is categorized into three domains: Bacteria, Archaea, and Eukarya.
- The domain Eukarya includes the kingdoms Protista, Fungi, Plantae, and Animalia.
Organism Characteristics
- Motile organisms can move independently.
- Autotrophic organisms produce their own energy, primarily through photosynthesis.
- Asexual reproduction requires only one parent cell.
- Eukaryotic cells contain membrane-bound organelles, including a nucleus.
- Prokaryotic cells lack membrane-bound organelles.
Cell Structure
- Multicellular organisms are composed of multiple cells, while unicellular organisms consist of a single cell.
Energy Acquisition
- Heterotrophic organisms obtain energy by consuming other sources, unlike autotrophs.
Classification System
- The classification system applies to both living and extinct organisms, allowing for the incorporation of new scientific discoveries.
- Organisms are organized based on similarities and evolutionary history.
- The system was refined by Linnaeus, but his work was not the initial development of classification.
Photosynthesis
- Plants are autotrophic because they perform photosynthesis, producing glucose as an essential energy molecule.
- Plants absorb CO2, contributing to the atmospheric balance.
Kingdom Characteristics
- Fungi: Eukaryotic, heterotrophic, with chitin in cell walls, and non-motile.
- Eubacteria: Prokaryotic organisms involved in yogurt and cheese production, existing within humans.
- Plantae: Multicellular autotrophs with chloroplasts that form the base of food webs.
- Archaebacteria: Prokaryotes that inhabit extreme environments.
- Animalia: Multicellular, heterotrophic eukaryotes that lack cell walls and chloroplasts and are capable of movement.
- Protista: A diverse group consisting of unicellular or multicellular eukaryotes representing a wide range of characteristics.
Classification Hierarchy
- The correct order of the biological classification system is: Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species.
