Document Summary

Metabolic cooperation: cooperation between prokaryotes allows them to use environmental resources they could not use as individual cells, in the cyanobacterium anabaena, photosynthetic cells and nitrogen-fixing cells called heterocysts (or heterocytes ) exchange metabolic products. Bacteria: bacteria include the vast majority of prokaryotic species familiar to most people, diverse nutritional types are represented among bacteria. Chlamydias: these bacteria are parasites that live within animal cells, example: chlamydia trachomatis causes blindness and nongonococcal urethritis by sexual transmission. Spirochetes: these bacteria are helical gram-negative heterotrophs, some are parasites, including treponema pallidum, which causes syphilis, and borrelia burgdorferi, which causes lyme disease. Cyanobacteria: these are gram-negative photoautotrophs that generate o2, plant chloroplasts likely evolved from cyanobacteria by the process of endosymbiosis, cyanobacteria are abundant components of freshwater and marine phytoplankton. The characteristics of lokiarchaeotes could shed light on the evolution of eukaryotes from their prokaryotic ancestors.
