What is the main difference between bacteria and most other living cells?

Bacteria as mentioned are prokaryotic, so have no nucleus and their DNA is contained in a mass of tangled strands. Many bacteria also contain plasmids, rings of parasitic DNA that are manipulated for many genetic engineering applications. Bacterial cells are generally much smaller than plant or animal cells and do not contain compartmentalized organelles(i.e mitochondria, endoplasmic reticulum, chloroplasts) as mentioned above. This makes them capable of reproducing and metabolizing much more quickly than larger cells.

Well.....bacteria are prokaryotic (or single-celled) organisms, where as most other living cells are eukaryotic (or many-celled) organisms. I'm pretty sure that's the main difference.





Ok, so I was wrong about eukaryotes being only many-celled organisms. But your question WAS what is the difference between bacteria and most other living cells and that difference is that bacteria are prokaryotic. So BLAH!
Reply:No no no. There are many single celled eukariotic organisms. Yeast are one example. Prokariotes do not have organells, nuclii, or chromosomes whereas eukariotic cells do.
