Detailed explanation-1: -Most motile bacteria move by means of flagella. The structures and pattern of movement of prokaryotic and eukaryotic flagella are different. Eukaryotes have one to many flagella, which move in a characteristic whiplike manner. The flagella closely resemble the cilium in structure.

Detailed explanation-2: -The flagellar motors of E. coli and Salmonella rotate in both counterclockwise (CCW) and clockwise (CW) without changing the direction of ion flow. E. coli and Salmonella cells can swim in a straight line by bundling left-handed helical filaments behind the cell body (run) when all of them rotate in CCW direction.

Detailed explanation-3: -The flagella have a whip-like appearance that helps to propel a cell through the liquid. Some special flagella are used in few organisms as sensory organs that can sense changes in pH and temperature. They are filamentous structures found in archaea, bacteria, and eukaryotes.

Detailed explanation-4: -The little whip-like structures that help prokaryotic cells move are called flagella. The flagella spin around and this helps to move the prokaryotes, like bacteria, along.

Detailed explanation-5: -Flagella are primarily used for cell movement and are found in prokaryotes as well as some eukaryotes. The prokaryotic flagellum spins, creating forward movement by a corkscrew shaped filament. A prokaryote can have one or several flagella, localized to one pole or spread out around the cell.
