Bacterial Classification:

Bacteria are unicellular prokaryotic microorganisms. Classification based on size is the most basic classification of bacteria.Bacteria are classified in 5 groups on the basis of size:Cocci (spherical)Bacilli (rod shaped) Spirilla (spiral shaped)Vibrio  (comma shaped) Spirochaetes (corkscrew shaped)

Organelles in Eukaryotic and Prokaryotic Organisms:

Eukaryotic organisms are defined by the presence of a nucleus and membrane bound organelles.Prokaryotic organisms do not contain a nucleus or membrane bound organelles.All cells (prokaryotic or eukaryotic) contain a cell membrane, DNA, cytoplasm and ribosomes.Eukaryotic organisms also contain the Golgi complex that is absent in prokaryotes.
