Prokaryotes are single-celled organisms that lack a nucleus and membrane-bound organelles such as mitochondria, chloroplasts, a golgi apparatus or an endoplasmic reticulum. Although prokaryotic organisms lack the organelles of eukaryotes, they can have membrane systems within their semi-rigid cell walls.
Material used to form the cell wall (in contrast to the cellulose used to form a eukaryotic plant cell wall) Binary fission Means by which prokaryotic cells divide - DNA is copied and the cell divides into two genetically identical daughter cells
Prokaryotes are single cell organisms. They do not have a membrane-bound nucleus or any mitochondria. Archaea and bacteria are the two domains of prokaryotes. For example, cholera and anthrax are two pathogenic bacteria.

Archaea are primitive micro organisms that have one cell and live in environments that are severe, such as those that are extremely salty or hot. They are any of a group of single celled prokaryotic organisms that have distinct molecular characteristics separating them from bacteria and from eukaryotes.
