I need help with bacteria-related project! Also involves archaea!?
I'm doing a project in my high school biology class. We need to pick a species from each of the 6 kingdoms and describe how each performs circulation, respiration, digestion, excretion, and reproduction. This includes which organs/cell parts each organism uses for each process.
I chose, for Archaea, Sulfolobus solfataricus, because it's supposed to be a model organism and well-studied. I can't find any good information on it though, beyond that its genome is well-mapped. (I'm guessing that's how it became a model organism.) There isn't enough information on how it performs these tasks. If you have a better organism for my purposes, please let me know.
For Eubacteria, I chose E. coli. I can't really find _how_ it performs these tasks - especially the cell parts used.
Everything I've read has been either too difficult for me to understand or too generic or vauge for me to use! Please help, and although I don't need to provide sources, it may help me if you do.

Both really use the same organelles to function. The slight difference between them is what they actually choose to eat or where they choose to live. Repiration means something completly different when we are talking about unicellular organisms. Keep that in mind. Respiration in cells actually means to eat in layman terms. It is accomplished by the mitochondria for the most part. Circulation is quite hard to define for them, for the most part they are filled with cytoplasm, which does stream in a particular direction, the cytoplasmic stream. Digestion is typically done inside of vesicles with the use of lysosomes. Excretion is done by vesicles. Reproduction tends to be asexual, that is they just reproduce themselves by themselves and produce two new cells. Although, there is DNA exchange which could be viewed as sexual reproduction depending on your opinion on it. This is known as bacterial conjugation, it can occur two more ways. But those get a little complicated.
