   The cell is the basic structural and functional unit of all forms of life. Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function. The term comes from the Latin word cellula meaning 'small room'. Most cells are only visible under a microscope.

   • DNA: circular (usually)
   • Typical organisms: bacteria, archaea

   • Type of nucleus: nucleoid region; no true nucleus
   • Typical size: ~ 1-5 μm [9]
