Prokaryotic vs Eukaryotic Cells Prokaryotic Primitive Simple DNA

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

Domains/kingdoms • Archae: single-celled, prokaryotic, extreme environments, look like bacteria • Bacteria (Eubacteria): true bacteria, single-celled, prokaryotic, includes E. coli • Eukarya (4 Kingdoms) 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)

Growth of phytoplankton and cyanobacteria (diatoms, algae) (bacteria)

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)
