is bathyarchaeota prokaryotic or eukaryotic
The Archaea domain has subcategories, but scientific sources differ on whether these categories are phyla or kingdoms. Cold Spring Harb. 1, 145 (2017). FEBS Lett. The evidence for this is the infoldings of the prokaryote plasma membrane lead to the compartmentalization of numerous cell organelles in eukaryotes. At some point, they were engulfed by larger prokaryotes and lived inside them. 69, 1738 (2013). The plant cell wall is primarily made of cellulose, rather than peptidoglycan. Biol. While every effort has been made to follow citation style rules, there may be some discrepancies. Likewise the bacteria, archaea are single-cell, simple prokaryotes, lacking the well-defined nucleus and other organelles. Is It the Flu, Stomach Flu, or Traveler's Diarrhea? 4, 346356 (2010).

However, some bacteria have been known to create iron or clay sort of shells that survive after the bacteria has died, creating a sort of model of the bacteria. The eukaryotic cell has a nuclear membrane that surrounds the nucleus, in which the well-defined chromosomes (bodies containing the hereditary material) are located. Google Scholar. Biol.

This study represents the first genome reconstructed purely from metagenomic data and uncovered the existence of homologues of the eukaryotic ubiquitin system in archaea. Nat. L.E., A.S., J.L. Among the prokaryotic communities, bacteria accounted for 85.5% of the total sequences, comprising 79.3% and 91.7% in KC-U and KC-I, respectively. During the genomic era, it became evident that eukaryotic cells possess a mixture of archaeal and bacterial features in addition to eukaryotic-specific features. This theory is supported by the fact that both mitochondria and chloroplasts contain their own DNA and that, like bacteria, they reproduce by splitting in two.

Also, this faster reproduction means that these cells can adapt faster as there are faster generations, which can be an advantage. They can maintain different environments in a single cell that allows them to carry out various metabolic reactions. Rivera, M. C. & Lake, J. Stud. Kozubal, M. A. et al. The proposed phylum Bathyarchaeota of the domain Archaea represents an evolutionary diverse group of microorganisms (previously denominated as Miscellaneous Crenarchaeotal Group, MCG) supposed to be widespread in nature [ 11, 12, 13 ].

More recently, it was suggested that additional candidate phyla such as Woesearchaeota, Pacearchaeota, Micrarchaeota and possibly Altiarchaeales are part of this group.
