Explanation:
Detailed explanation-1: -Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties.
Detailed explanation-2: -Bacteria lack a membrane-bound nucleus and other internal structures and are therefore ranked among the unicellular life-forms called prokaryotes.
Detailed explanation-3: -Bacteria are like eukaryotic cells in that they have cytoplasm, ribosomes, and a plasma membrane. Features that distinguish a bacterial cell from a eukaryotic cell include the circular DNA of the nucleoid, the lack of membrane-bound organelles, the cell wall of peptidoglycan, and flagella.
