A prokaryotic cell (e.g. a bacterial cell).
The nucleus of the cell contains the genome.
A nucleus and membrane bound organelles
A unicellular organism lacking a nucleus is classified as a prokaryotic cell. Prokaryotes, such as bacteria and archaea, have a simpler structure compared to eukaryotic cells and do not possess membrane-bound organelles. Their genetic material is typically organized in a single circular chromosome located in a region called the nucleoid. Prokaryotic cells reproduce asexually, primarily through binary fission.
Prokaryotic cells lack membrane-bound organelles, including a distinct nucleus. Their genetic material is found in the nucleoid region of the cell, which is not enclosed by a nuclear membrane.
The most common example of an anucleated (nucleus-lacking) cell is a mature mammalian erythrocyte (red blood cell). Erythrocytes also lack mitochondria. This causes them to be short-lived. They are specialized solely to facilitate the transport of oxygen to bodily cells, and carbon dioxide away from them, via hemoglobin.
Red blood cell
vacuole
A prokaryote.
Prokaryotic cells. These cells are usually found in bacteria and archaea and are characterized by their simple structure and lack of a defined nucleus.
When a bacteria cell lacks a nucleus (like most bacteria do), it is said to be a prokaryotic cell.
The presence or absence of a nucleus is the major characteristic that classifies a cell as either prokaryotic (lacking a nucleus) or eukaryotic (containing a nucleus). Eukaryotic cells also typically have membrane-bound organelles, while prokaryotic cells do not.
One with no nucleus, or complex organelles
Organisms that lack a nucleus is called a Prokaryote. All prokaryotic cells are bacteria. :)
