Bacteria are unicellular organisms, meaning they consist of a single cell. This prokaryotic cell structure lacks a defined nucleus and membrane-bound organelles, distinguishing them from eukaryotic cells. Bacterial cells typically have a cell wall, plasma membrane, cytoplasm, ribosomes, and genetic material in the form of circular DNA. Their simple structure allows them to reproduce rapidly and adapt to various environments.
