Hint: Prokaryotes are unicellular creatures with no membrane-bound structures, the nucleus being the most notable. Despite the lack of membrane-bound structures in prokaryotic cells, they do have different cellular areas. The nucleoid is a place in prokaryotic cells where DNA bundles together.

Complete answer:
Bacteria and Archaea, the two prokaryotic kingdoms, grouped early in the evolution of life. Bacteria can range from pathogens that cause disease to beneficial photosynthesizers and symbionts. Archaea are also varied, but none of them are harmful, and many of them live in harsh conditions. Metagenomics is a DNA sequencing technique that allows scientists to find new species of bacteria and archaea, including those that can't be cultivated.

Prokaryotes are divided into two kingdoms. These are bacteria (sometimes known as eubacteria) and archaebacteria (or the Archaea).
Prokaryotes, which include bacteria and archaea, can be found practically anywhere — in ecosystems, on surfaces in our houses, and even inside our bodies! Some exist in conditions that are too hostile for other organisms to survive, such as scorching vents on the ocean floor.
 However, research conducted in the 1970s by microbiologist Carl Woese revealed that prokaryotes are separated into two distinct lineages, or lines of descent: Archaea and Bacteria. Today, these groupings are thought to make up two of the three life domains. All eukaryotes, such as plants, animals, and fungi, are included in the third domain (Eukarya).

Note:-
The bacteria in the other four major categories are just as varied. Chlamydias are diseases that dwell inside host cells, whereas cyanobacteria are photosynthetic bacteria that produce much of the oxygen on the planet. Spirochetes comprise both benign and hazardous bacteria, such as the Lyme disease-causing Borrelia burgdorferi. Gram-positive bacteria, which include everything from probiotic bacteria in yoghurt to anthrax-causing Bacillus anthracis, are the same.
