A prokaryote is an organism that lacks a distinct nucleus and other organelles due to the absence of internal membranes. Bacteria and archaea are 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 cellâs primary barrier to the environment.
That depends who you ask! In general, prokaryotes are single-celled organisms. However, there's increasing evidence that some groups of prokaryotic cells can organize to form structures that resemble multicellular organisms. Whether this counts as real multicellularity is a question hotly debated by researchers today.
