Question

Describe the traits that separate Archaea from other single-celled organisms.

Answer 1

Archea too belong to the Prokaryotes (other single celled organisms like bacteria). However archea vary in functions from other single celled organisms. Traits of archea resemble more with Eukaryotes.

Some of the major traits that separate archea from other single celled organisms can be as;

* Archea are single celled and simple structures while as other single celled like bacteria have complex structures.

* Archea are usually found in extreme conditions like hot springs, ocean depths.

* Cell wall in archea made up of pseudopeptidogylcan , while as in other single celled organisms it is made of peptidogylcan.

* Archea do not follow glycolysis or Krebs cycle but follow some similar pathways.

* Archea reproduce by asexual methods like binary fission, fragmentation, budding. On the other hand

Other single celled organisms have spore formation to grow in extreme conditions.

* In archea thymine is absent in tRNA, while it is present in other single celled organisms.

* Introns are present in archea and have not been found in other single celled organisms.

* RNA polymerase is complex in archea.

* Archea are non pathogenic while as other single celled organisms are pathogenic.
