compare archaebacteria and eubacteria
Answers
Answer:
Archaebacteria
Archaebacteria are the single-celled microorganisms, living in extreme environments. They form a domain of kingdom monera. Archebacteria are considered to be evolved just after the first life on earth. Hence, they are called ancient bacteria. Archaebacteria are found in hot springs, salt lakes, oceans, marshlands and soils. They are also found in human skin, oral cavity and colon as well. Archaebacteria play a vital role in carbon cycle and nitrogen cycle. Their pathogenic or parasitic effect is still not observed. Archaebacteria are metabolically diverse, using a variety of substrates as their energy and carbon sources. Asexual reproduction of archaebacteria is identified, occurring by binary fission, budding and fragmentation.
eubacteria
Eubacterial are a more complex domain of kingdom monera. They are found in most of the habitats on earth like soil, water and inside or outside of large organisms. Since eubacteria do not consist of membrane-bound organelles, almost all the metabolic reactions take place in the cytoplasm. Some eubacteria are involved in the nitrogen cycle as well. They also exhibit both parasitic and pathogenic effects on their host organisms. Other than usual asexual reproduction methods, eubacteria exhibit sexual reproduction methods like conjugation.
