LEVELS OF CLASSIFICATION

DOMAINS

• There are three domains
• Bacteria
• Archae
• and Eukarya

Bacteria

• composed of organisms that are more common than archaea and live almost anywhere.
• there is more bacteria in a persons mouth than people in the world.
• many are decomposers, some are photosynthesizers, and a few cause disease.
• unicellular, absorptive-heterotrophic, photo-autotrophic, or chemoautotrophic
• lack sexual reproduction Bacteria is in the kingdom eubacteria

Eukaryote

• is any organism whose cells contain a nucleus
• and other structures enclosed within membranes.
• cell division in eukaryotes is different from that in organisms without a nucleus
• There are two types of cell division processes Mitosis and meiosis.
• Anamalia planate Protista and fungi.

Archaea

• genetically more similar to eukaria than to bacteria
• tolerate harsher environments than most other prokaryotes and all eukaryotes
• prokaryotic like bacteria, but biochemicals of cell walls
• in kingdom achaebacteria
