Prokaryotic vs. Eukaryotic Cells Prokaryotic Primitive Simple DNA is in nucleiod region No membrane bound organelles Smaller Bacteria, Archae Eukaryotic modern complex DNA is in nucleus membrane bound organelles Larger Protists, Fungi, Plants Animals Prokaryotic Cell Eukaryotic Cell 6 kingdoms • Archae: single-celled, prokaryotic, extreme environments, look like bacteria • Bacteria (Eubacteria): true bacteria, single-celled, prokaryotic, includes E. coli • Protista: single-celled plants and animals, eukaryotic, includes Paramecium (pond water organisms) • Fungi: multicellular, eukaryotic, chemotrophs, decompsers, includes: yeasts, molds and mushrooms • Plantae: multicellular, eukaryotic, autotrophs (photosynthesis), includes: grass, shrubs, trees • Animalia: multicellular, eukaryotic, heterotrophs, motile, includes: you! 3 Domains 1. Archae: Prokaryotic cells Extreme environments 2. Bacteria: Prokaryotic cells Extreme environments 3. Eukarya: Eukaryotic Cells Kingdoms: Protists, Fungi, Plants, Animals Archae: Prokaryotic cells Extreme environments Bacteria: Prokaryotic cells Extreme environments 5 Functions of Bacteria 1. Decomposers 2. Soil producers 3. Produce organic material 4. Facilitate digestion 5. Pathogens (disease causing organisms) Unnumbered Figure 15_UN310 Protista Single celled plants and animals Amoeba, Paramecium, Euglena Red Tide Dinoflagellates Growth of phytoplankton and cyanobacteria Fungi Eukaryotic Multi-cellular Chemotrophs Yeasts, molds and Mushrooms Symbiotic Relationships 1. Mutualism (both benefit) 2. Parasitism (one benefits, one is harmed) 3. Commensalism (one benefits, one not affected)
