Which of the following is true of the flagellum in eukaryotes?     It is a long, thin extracellular (exterior) structure, with a basal motor embedded in the cell membrane/cell wall.     It is identical to the archaeal flagellum (archaellum) in composition and structure, but very different in composition and structure from bacterial flagella.     It is a long, thin structure containing bundles of microtubules and motor proteins, all within the plasma membrane.     Eukaryotic cells do not possess flagella.

Archaeal cell structure

Bacteria and archaea are two different prokaryotic domains that, along with eukarya, make up the three domains of life. Archaeal organisms can be found all over the biosphere. Many genera are extremophiles, meaning they thrive in extreme environments such as extremely high temperatures, high salinity, or pH extremes. Bacterial and archaeal cells are characterized by the absence of a nucleus and membrane-bound organelles.
