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.
Just about every living organism on Earth can be placed in one of two classes: prokaryotes and eukaryotes. A prokaryote is a cell without a nucleus and eukaryotes are cells that contain nuclei. There's one quick test to distinguish prokaryotes from eukaryotes: if you can see a single organism, it's a eukaryote. All prokaryotes are single-celled organisms. Some eukaryotes are also single-celled organisms, but every multi-celled organism is eukaryotic.
