Are mostly cells that live in extreme environments. They are rare because they live with other organisms and the organism has to live in the extreme environments.
Are composed of organisms much more common than Archaea and live almost anywhere.
It includes all of the organisms with eukaryotic cells, that is, those with membranous organelles (including mitochondria and chloroplasts).
Archaea are a domain of single-celled microorganisms. They have no cell nucleus or any other organelles inside their cells.
Very small, simple, lack membrane-bound organelles, and have strong cell walls.
mostly unicellular, some are multicellular (algae). Can be heterotrophic or autotrophic. Most live in water (though some live in moist soil or even the human body). ALL are eukaryotic (have a nucleus). A protist is any organism that is not a plant, animal or fungus.
The organisms in kingdom fungi include mushrooms, yeasts, molds, rusts, smuts, puffballs, truffles, morels, and molds.
Can make its own food from the sun and has cell walls.
Are multicelluar, consume other organisms to get energy, and are what we are.
