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:

1. Cocci (spherical)
2. Bacilli (rod shaped)
3. Spirilla (spiral shaped)
4. Vibrio (comma shaped)
5. 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.
