are halophiles unicellular or multicellularUncategorized

Halophiles can be found mostly in the domain Archaea, which contains single-celled ancient prokaryotic microorganisms. Protozoa have been traditionally divided based on their mode of locomotion: flagellates produce their own food and use their whip-like structure to propel forward, ciliates have tiny hair that beat to produce movement, amoeboids have false feet or pseudopodia used for feeding and locomotion, and sporozoans are non-motile. They have adapted to handle salt concentrations that would kill other breeds of sheep.[18]. Asexual reproduction generates genetically __________ offspring, whereas sexual reproduction produces genetically _________ offspring. Microorganisms are divided into seven types: bacteria, archaea, protozoa, algae, fungi, viruses, and multicellular animal parasites ( helminths ). The first strategy is employed by some archaea, the majority of halophilic bacteria, yeasts, algae, and fungi; the organism accumulates organic compounds in the cytoplasmosmoprotectants which are known as compatible solutes.
