    friend,,,

    Bacteria are generally simple structures. The bacterial cell lacks a membrane-bound nucleus. Because of this, bacteria are described as prokaryotes.
    Bacteria have been on the Earth for millions of years. It wasn't until the late 1600s that scientists discovered bacteria.




    The Function and Composition of Flagella:
    The purpose of Flagella (sing., flagellum) is motility.
    Flagella are long appendages which rotate by means of a "motor" located just under the cytoplasmic membrane.
    Bacteria may have one, a few, or many flagella in different positions on the cell.




    Flagella are filamentous protein structures attached to the cell surface that provide the swimming movement for most motile procaryotes.
    Procaryotic flagella are much thinner than eucaryotic flagella, and they lack the typical "9 + 2" arrangement of microtubules.
    The diameter of a procaryotic flagellum is about 20 nanometers, well-below the resolving power of the light microscope
