WebOct 4, 2024 · Found mainly in Gram-negative organisms, fimbriae or pili (singular: pilus) are hair-like filaments (tiny hollow projections) that extend from the cell membrane into the external environment. A pilus is composed of subunits of the protein pilin. Fimbriae (pili) are shorter, straighter, and more numerous than bacterial flagella. E.coli bacteria ... WebBacterial flagella are filamentous organelles that drive cell locomotion. They thrust cells in liquids (swimming) or on surfaces (swarming) so that cells can move toward favorable environments. At the base of each flagellum, a reversible rotary motor, which is powered by the proton- or the sodium-motive force, is embedded in the cell envelope. ...
