Transcript E. coli

6 Kingdoms
Only two ?
-for hundreds of years there were only 2
kingdoms: Plantae (plants) and Animalia (animals)
-eventually new species were discovered that
didn't quite fit either one
-new kingdoms had to be developed
-there are currently 6 kingdoms into which we
classify every known species
Archaebacteria
-have been on earth at least 3 billion years
-name means "ancient bacteria"
-able to survive in extremely harsh environments
Ex: hot springs in Yellowstone Park or volcanic
vents in the ocean floor
Areopyrum lives
in volcanic vents.
Eubacteria
-all other types of bacteria
-live in soil, water, inside the human body
-Escherichia coli (E. coli ) can be found in
human intestines
E. coli produces vitamin K.
Causes "food poisoning".
Can be easily altered
through genetic engineering.
Protista (protists)
-single-celled or simple multicellular organisms
-eukaryotic, having evolved from bacteria about 2
billion years ago
-includes all eukaryotes that are not plants,
animals, or fungi
-3 types: Protazoa (animal-like),
Algae (plant-like), Slime & Water
Molds (fungi-like)
Giant Kelp
Paramecium
Euglena
Plantae (plants)
-complex
-multicellular
-usually green
-use photosynthesis
to make glucose
Ex: Trees, shrubs,
flowering plants
Fungi
-complex
-multicellular
-use digestive juices
to breakdown materials
and absorb their nutrients
Ex: molds & mushrooms
Animalia (animals)
-complex & multicellular
-can move
-have a nervous system
-cells lack a cell wall
Ex: birds, fish, reptiles,
insects, mammals
