Study Notes
Classification of Organisms
- Living organisms are categorized into taxonomic kingdoms of life.
- The most basic category for organisms is a kingdom.
- Most scientists divide organisms into five major kingdoms.
- Prokaryotic organisms (bacteria and blue-green algae) are single-celled, without a nucleus.
- Eukaryotic organisms are single or multicellular, containing a nucleus and other membrane-bound organelles.
- Archaebacteria and Eubacteria are prokaryotic.
- Eubacteria contain simple multicellular or unicellular organisms
- Protista includes simple multicellular or unicellular organisms, exhibiting either autotrophic or heterotrophic nutrition.
- Plantae are multicellular, autotrophic organisms (photosynthesis), characterized by absorptive nutrition.
- Fungi are multicellular, heterotrophic organisms (absorptive nutrition).
- Animalia are multicellular, heterotrophic organisms (ingestive nutrition).
