Bacteria have which kind of cell type?

Explanation:
Bacteria have prokaryotic cells. That means they lack a defined nucleus and other membrane-bound organelles. Their DNA is typically in a single circular chromosome located in a region called the nucleoid, and the cell is generally smaller with ribosomes of a different size than those in eukaryotes. Their cell walls, when present, commonly contain peptidoglycan. This prokaryotic organization distinguishes bacteria from eukaryotic cells, which have a nucleus and various membrane-bound organelles. (Archaea are also prokaryotes, but have distinct biochemistry.) So describing bacteria as prokaryotic cells best fits their cellular structure.
