Proteobacteria
 Definition
Putplr bsvyrtis. Gram-negative. photoautotrophs, photoheterotrophs, chemoheterotrophs. Ancestors of mitochondria.
Term
Green bacteria
 Definition
Photosynthesis. Chrophyll, not the one in plants. Do not release oxygen. Sulfurous and nonsulfurous categories.
Term
Cyanobacteria

 Definition
Structurally unusual --- lack peptidoglycans.
Term
Other terms
 Definition
Term
Chemoautotrophs
 Definition
Oxidize inorganic substances and use C02 as energy source.
Term
Chemoheterotrophs
 Definition
Oxidize organic molecules for energy, obtain organic carbon.
Term
Photoautotrophs
 Definition
Photosynthetic, C02 as energy source.
Term
Photoheterotrophs
 Definition
Photosynthetic, Organic carbon as energy source.
Term
Gram positive v. negative
 Definition
Negative has thin layer of peptidoglycans, outer membrane with lipopolysaccharides. Postive just has peptidoglycans.
