Summary Introduction
To provide: The reason for which bacteria can
Introduction: All life forms are classified into three main domains, namely, archaea, bacteria, and eukarya. These three domains are classified based on the type of cells of the organisms. The prokaryotes are unicellular microorganisms that lack membrane-bounded organelles and nucleus.
