Discuss the similarities and differences between organisms in the domains Bacteria and Archaea - Essay Example Archaea cell wall does not have a cell membrane and peptidoglycan and utilizes ether-linked lipids compared to an ester-linked lipids used by bacteria (Decker and Hinton, 2013). Archaea flagella developed from type IV pili bacterial while bacterial flagella advanced from type III secretion system. Bacterial flagellum is hollow and appears alike a stalk assembled by subunits that move up freely on the central pore causing a growth on the tip of flagella while, in archaea, flagella subunits grow at the base The reproduction of Archaea is asexual utilizing binary fission process, fragmentation and budding. Bacterial reproduction is asexually through a process binary fission, fragmentation budding, but bacteria show a unique ability by forming spores that enable them remain dormant for many years, characteristics not displayed by Archaea. Growth of bacteria follows three phases, the lag phase where cells adaptation to the environment, log phase where exponential growth happens and stationary phase when depletion of nutrients occur (Szukics, Hackl,and Zechmeister, 2012). Archaea survives in places and environment of extreme and cruel conditions like springs, marshlands, salt lakes, oceans, ruminants gut, and humans. Bacteria are everywhere and found in soil, radioactive waste, hot springs, organic matter, plants and animals bodies. These two microorganisms have a difference in biochemical and genetic ways (Mao, Yannarell, Davis, and Mackie 2013). Szukics, U., Hackl, E., Zechmeister-Boltenstern, S., & Sessitsch, A. (2012).
