Structure of a prokaryotic bacteria cell

Prokaryotes (or Monera) are some of the simplest living things. They are unicellular organisms and they include two major divisions of simple living beings: bacteria, and Archaea. They generally do not have a cell nucleus, nuclear membrane or cell organelles, however a small number of exceptions have been found. Prokaryotes possess genetic material in the form of a single DNA loop called a Nucleoid that floats around freely inside the cell. Bacteria include the Cyanobacteria (formerly known as blue-green algae due to their photosynthetic capacity).
