Detailed explanation-1: -Bacteria are single celled microbes that lack a nucleus. Archaea are like bacteria, but they have different structures and properties. This gives them the ability to live in extreme environmental conditions. Protozoa are unicellular microorganisms that have nuclei.
Detailed explanation-2: -All bacteria are unicellular, and all are prokaryotic. Prokaryotes are organisms that are made of one prokaryotic cell, which is a cell type that lacks membrane-bound organelles and has no true nucleus.
Detailed explanation-3: -No, bacteria are prokaryotic organisms, meaning that they are all single-celled. However, they do have tendencies to form colonies. So, while they do live in groups, they are all completely independent organisms. Only eukaryotic organisms can be multi-cellular.
