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 Decomposers Soil producers Produce organic material Facilitate digestion Pathogens (disease causing organisms)
