Topic: Six Kingdoms of Life (Chpt 18.3)

Six Kingdoms - organized according to type of cells, ability to make food, number of cells in body  Archaebacteria  Eubacteria  Protists  Fungi  Plants  Animals Monera

1. Archaebacteria  prokaryote (Lacks a nucleus); Unicellular  Some Autotrophs, some Heterotrophs  Oldest form of life “ancient bacteria”  Found in extreme environments  Geysers  Hot springs  Volcanic ocean vents

Grand Prismatic Spring in Yellowstone National Park. The brilliant colors observed in the spring, are attributed to archaebacteria Sulfolobus archae

2. Eubacteria  prokaryote (Lacks a nucleus); Unicellular  Some Autotrophs, some Heterotroph  Most familiar bacteria (examples)  Streptococcus  Lactobacillus  Staphylococcus  Found in more neutral environments  Second oldest form of life

streptococcus lactobacillus acidophilus

3. Protists  Eukaryotes; Most unicellular, some multicellular  Some Autotrophs and some Heterotrophs  Common Protists include:  Protozoa  Amoeba and Euglena  “Odds and Ends” kingdom- they are all pretty different from one another.  All microscopic organisms that are not plants, not animal, not bacteria, and not fungi.

Amoeba Volvox Euglena

4. Fungi  All Eukaryotes  Most are multi-cellular, some like yeast are unicellular  Heterotrophs  Examples: mushrooms, yeast, mold, and mildew  Some cause diseases – ringworm, and athlete’s foot  Eat dead or decaying organisms

Bracket fungus ringworm Amenita Athlete's foot

5. Plants  Eukaryotes  Multi-cellular organisms  Autotrophs  Examples: roses, trees, and bushes  Producers (make their own food)  Second largest kingdom  Without plants life as we know it would not exist.

Animals  Eukaryotes  Multi-cellular  Heterotrophs  Examples: Humans, fish, ants, birds  Largest kingdom  Consumers – must eat food for energy  Over 1 million known species
