The flagellum in archaea is called the archaellum to note its difference from the bacterial flagellum. [7] [8] Eukaryotic flagella and cilia are identical in structure but have different lengths and functions. [9] Prokaryotic fimbriae and pili are smaller, and thinner appendages, with different functions. Cilia are attached to the surface of ...
Eukaryotic flagella—those of animal, plant, and protist cells—are complex cellular projections that lash back and forth. Eukaryotic flagella are classed along with eukaryotic motile cilia as undulipodia [17] to emphasize their distinctive wavy appendage role in cellular function or motility. Primary cilia are immotile, and are not undulipodia.
Eukaryotic flagella are complex cellular projections that lash back and forth, rather than in a circular motion. Prokaryotic flagella use a rotary motor, and the eukaryotic flagella use a complex sliding filament system. Eukaryotic flagella are ATP-driven, while prokaryotic flagella can be ATP-driven (archaea) or proton-driven (bacteria). [124]

In most such organisms, one or more flagella are located at or near the anterior of the cell (e.g., Euglena). Often there is one directed forwards and one trailing behind. Many parasites that affect human health or economy are flagellates in at least one stage of life cycle, such as Naegleria, Trichomonas and Plasmodium.
The flagellum is a rotating structure driven by a reversible motor at the base that uses the electrochemical gradient across the membrane for power. [148] The different arrangements of bacterial flagella: A-Monotrichous; B-Lophotrichous; C-Amphitrichous; D-Peritrichous. Bacteria can use flagella in different ways to generate different kinds of ...
Difference of beating pattern of flagellum and cilium. Flagella are used in prokaryotes (archaea and bacteria) as well as protists. In addition, both flagella and cilia are widely used in eukaryotic cells (plant and animal) apart from protists. The regular beat patterns of eukaryotic cilia and flagella generates motion on a cellular level.
Movement of the flagellum draws water through the collar, and bacteria and detritus are captured by the microvilli and ingested. [12] Water currents generated by the flagellum also push free-swimming cells along, as in animal sperm. In contrast, most other flagellates are pulled by their flagella. [citation needed]
