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
