Document Summary

One of the three taxonomic domains of life. Member of the domain bacteria or archaea. Unicellular organism lacking a nucleus and containing relatively few organelles or cytoskeletal components. Several types of protists can cause human disease: also in crops. Has evolved resistance to drugs used to control its growth. Because it evolves so quickly, researchers have been unable to develop vaccine against it. Natural selection has favored mosquitos tat are resistant to the insecticides used to attempt to control the spread of malaria. Protists play very important role in the global carbon cycle. Function as primary producers and as decomposers and scavengers. Mitochondria originated when bacteria cell took up residence inside another cell. Symbiosis: when individuals of two different species live in physical contact. Endosymbiosis: when organism of one species lives inside the cells of n organism of another species. Archaeal host and bacterium: host supplied the bacterium with protection and carbon compounds, bacterium produced much more atp.
