|
|
|
Prokaryote |
Organisms with no nucleus |
|
|
|
Archaea |
Single celled organisms that lack a nucleus but are more closely related to eukaryotes than to bacteria - found in extreme locations |

|
|
Eukaryotes |
Organisms whose dna is contained with in the nucleus, some are unicellular, others multicellular, typically larger and more complex than bacteria or archaea |
|
|
|
Protists |
Simplest eukaryotes as a group they vary a great deal, single celled consumers to giant, multicelled producers |
|
|
|
Prostists |
A eukaryote that is not a plant, animal or fungus |
|
|
|
Fungi |
Multicelled eukaryotes (mushrooms) many are decomposers, all are consumers that secrete substances that break down food outside the body and absorb released nutrients |
|
|
