- Prokaryotes are organisms whose cells do not contain a distinct nucleus, bounded by a nuclear envelope, in contrast to eukaryotic organisms that do have distinct nuclei. Prokaryotes include both the bacteria and the archaea, which appear to be only distantly related to bacteria.
Prokaryote, also spelled procaryote, Bacteria are among the best-known prokaryotic organisms. The lack of internal membranes in prokaryotes distinguishes them from eukaryotes. The prokaryotic cell membrane is made up of phospholipids and constitutes the cell’s primary osmotic barrier. The cytoplasm contains ribosomes, which carry out protein synthesis, and a double-stranded deoxyribonucleic acid (DNA) chromosome, which is usually circular. Many prokaryotes also contain additional circular DNA molecules called plasmids, with additional dispensable cell functions, such as encoding proteins to inactivate antibiotics. Some prokaryotes have flagella. Prokaryotic flagella are distinct in design and movement from the flagella found on some eukaryotes.

Sir Jaise k aap ne Kaha k Archea aur eukarya aapas mein related Hain jab k similarities Tu almost Archea ki bacteria k saath milte Hain..
I will wait for answer 😊
Archea ka genes produce enzymes particularly polymerase used in metabolic activities during translation and transcription as present in eukaryotic organisms ❤❤
