They are clones of eachother.
Microscopes powerfule enought o see them
Names base on morphology but diversity that is underneath

Metabolism Cocci Spirillai Bacilli bacteria of different structures have the same organization
Flagella allowing them to be mobile
All of taxonomy and classification done in biology, it does not work
in bacteria, but because of some established genus species
names are kept Squares Figure 20.2 BIO1130 Organismal Biology 10 Université d’Ottawa / University of Ottawa 2:39 PM No subdivision of the cytoplasm into any compartemnts
