Do all prokaryotes have flagella? All prokaryotic cells are encased by a cell wall. ... Flagella and some pili areused for locomotion, fimbriae help the cell stick to a surface, and sex pili are used for DNA exchange. Most prokaryotic cells have a single circular chromosome. They may also...
Do all bacteria have pili? Pilin refers to a class of fibrous proteins that are found in pilus structures in bacteria. ... Although not all bacteria have pili or fimbriae, bacterial pathogens often use their fimbriae to attach to host cells. What are the two types of pili? There are two...
cell membrane, cytoplasm, ribosomes and the chromosome, although some bacteria cells also contain a plasmid or extra-cellular structures like a capsule, fimbriae and flagella. Unlike a eukaryotic cell, which does posses a nucleus, a bacteria does not ...

They also found that biofilms consisted of small aggregates, usually containing less than a thousand bacteria, and they were not adherent to the epithelium. These findings illustrate that patients with chronic infections carry a multitude of biofilm structures. We imaged P. aeruginosa biofilms in a...
