Archaebacteria
•
•
•
•
•
•
Means Ancient Bacteria
Prokaryotes­ do not have a nucleus
Unicellular
Autotrophs or heterotrophs
Photosynthetic and chemosynthetic
Live in harsh environments:
­Ocean floor
­salt water
­hot springs
­intestines
­Swamps
2
Eubacteria
• Prokaryotes
• Unicellular
• Autotrophs or heterotrophs
• Photosynthetic and chemosynthetic • Strong cell walls
• Some cause strep throat and pneumonia but most are harmless.
• Live in all environments except harsh ones.

•
Eukaryotes­ Cells with a nuclei
Unicellular or multicellular
Autotrophs or heterotrophs
Lack complex organ systems
­seaweed

Eukaryotes
Heterotrophs
Absorb nutrients from organic molecules
Do not move
Most multicellular and a few unicellular

Eukaryotes
Multicellular
Autotrophs­ Conduct photosynthesis
Contain chloroplasts and a cell wall.
Complex organ systems.
more than 250,000 species
Feed almost all heterotrophs on Earth
