Classification of Life: Kingdoms and Domains Ch. 18-3 Be able to distinguish kingdoms and domains based on traits
Science of classification = taxonomy= the use of a system to classify things We use a variety of characteristics to classify organisms Morphological = how they look Physiological = how their bodies work Genetic = how does their DNA look
Changing Number of Kingdoms Changing Number of Kingdoms First Introduced Names of Kingdoms 1700s Plantae Animalia Late 1800s Protista 1950s Monera Fungi 1990s Eubacteria Archaebacteria
Recent Changes… Linnaeus’s classification scheme has been modified to create 3 domains that are higher than the Kingdoms. Archaea = similar to Eubacteria with a few differences. Now considered separate from Eubacteria. Includes Kingdom Archaebacteria Bacteria = includes Kingdom Eubacteria (Monera) or prokaryotes 3) Eukarya = includes several kingdoms (eukaryotes)
Kingdoms of eukaryotes Plantae = multicellular, photosynthesis Animalia = multicellular Fungi = Most multicellular (mushrooms, molds, yeast) Protista = most unicellular, come multi-cellular or colonial (amoeba, algae, kelp, slime mold) See figures 18-11 and 18-12 in textbook for details and easy comparison of all domains and kingdoms
