WebApr 6, 2024 · Bacteria are the smallest free-living (self-replicating) organisms. Most swim in aqueous media by rotating flagella, long thin filaments driven at their base by rotary motors. In most cases, the filaments are helical and extend out into the external medium; in some cases, as in spirochetes, they remain inside the cell (under the outer membrane ... dr damore san jose
