What are some things that make bacteria such unique organisms?

They are single-celled, there genetic material is not enclosed in a membrane, they basically lack most organelles found in eukaryotes except ribosomes and mitochondria

What are some things that make bacteria such unique organisms?
They are unique for many reasons. Some of these reasons include: They lack a nucleus, they usually only have 1 circular piece of DNA, they are able to use a variety of terminal electron acceptors, and some can live in hot springs, salty conditions, and really low temperatures. Hope this helps.
