Microorganisms are beneficial in producing oxygen, decomposing organic material, providing nutrients for plants, and maintaining human health, but some can be pathogenic and cause diseases in plants and humans. Bacteria can be further divided based on their response to gaseous oxygen into the following groups: aerobic (living in the presence of oxygen), anaerobic (living without oxygen), and facultative anaerobes (can live in both environments). Archaebacteria, cyanobacteria and eubacteria are the three types of monerans. Answer the following question: Brine shrimp and the larvae o brine flies are also eukaryotic halophiles. Halophiles live in extreme environments, but what are these extreme places? While some prokaryotes are quite troubling to humans because of the diseases they can cause, many Bacteria are extremely beneficial. The presence of this adaptation in three distinct evolutionary lineages suggests convergent evolution of this strategy, it being unlikely to be an ancient characteristic retained in only scattered groups or passed on through massive lateral gene transfer. The halophiles are mostly found in such salty environments as the Dead Sea while methanogens can be found in animal intestines (cows and . Halophilic Eukarya Dunaliella salina and Dunaliella bardawil are widely exploited for the production of carotenoids.

It is very disputed under which domain it belongs. ________ is a procedure by which scientists determine what type of bacteria they have. through cell-division. Microorganisms or microbes are microscopic organisms that exist as unicellular, multicellular, or cell clusters. Although all cells have organelles in common, the number and types of organelles present reveal how the cell functions. An algae in this form is called a gametophyte. While comparatively few studies of this type have been performed, results from these suggest that some of the most readily isolated and studied genera may not in fact be significant in the in situ community. Diatoms are a type of free-floating protists commonly referred to as algae. It is the kingdom eukaryotic unicellular or multicellular organisms. Halophiles are typically categorized as slight, moderate, or extreme based on the amount of salt they can tolerate in their environment. The carotenoids produced by the organism in its algal chloroplasts give it a distinct red color. On this Wikipedia the language links are at the top of the page across from the article title.
