The domain bacteria are prokaryotes, single-celled organisms that have no membrane-bound organelles and make up a large proportion of living organisms. The domain bacteria contains five major groups: proteobacteria, chlamydias, spirochetes, cyanobacteria, and gram-positive bacteria. A prokaryote is a cellular organism that lacks a nuclear membrane-enclosed nucleus. The word prokaryote comes from the Greek πρό and κάρυον. In the two-empire system arising from the work of Édouard Chatton, prokaryotes were classified within the empire Prokaryota. But in the three-domain system, based upon molecular analysis, prokaryotes are divided into two domains: Bacteria and Archaea. Organisms with nuclei are placed in a third domain, Eukaryota.

The Archaea are prokaryotes that inhabit extreme environments, such as inside of volcanoes, while Bacteria are more common organisms, such as E. coli. 2019-10-30 · Prokaryotes are single-celled organisms that are the earliest and most primitive forms of life on earth. As organized in the Three Domain System, prokaryotes include bacteria and archaeans. Some prokaryotes, such as cyanobacteria, are photosynthetic organisms and are capable of photosynthesis. 2010-07-12 · The 3 domains are Bacteria, Archaea, and Eukarya. The two domains that include all prokaryotes are the first two (Bacteria and Archaea).

They have a single piece of circular DNA in the nucleoid area of the cell. Most prokaryotes have a cell wall that lies outside the boundary of the plasma membrane. Some prokaryotes may have additional structures such as a capsule, flagella, and pili.

One domain containing prokaryotes is

However, work by microbiologist Carl Woese in the 1970s showed that prokaryotes are divided into two distinct lineages, or lines of descent: Archaea and Bacteria. Today, these groups are considered to form two out of three domains of life. One of the three domains of life; contains prokaryotic cells that often live in extreme habitats and have unique genetic, biochemical, and physiological characteristics; its members are sometimes referred to as archaea. 1. "Domains Archaea and Bacteria" is the one among the following choices given in the question that contain only prokaryotes.
