1.	Motile cells are biflagellated but the two flagella are an equal im
Answer» A\xa0flagellum\xa0(/fləˈdʒɛləm/; plural:\xa0flagella) is a lash-like appendage that protrudes from the\xa0cell\xa0body of certain bacteria and eukaryotic\xa0cells\xa0termed as flagellates. A flagellate can have one or several\xa0flagella.\xa0Flagella\xa0are key structures concerned\xa0with bacterial motility. Nevertheless,\xa0bacteria\xa0that lack\xa0flagella\xa0may still be\xa0motile. A type of gliding\xa0motility\xa0can be achieved by the flexible movement of the whole cell. This is mainly observed on solid media, whereas flagellar motion is common to liquid environments.\xa0The primary purpose of\xa0cilia\xa0in mammalian cells is to move fluid, mucous, or cells over their surface.\xa0Cilia\xa0and\xa0flagella\xa0have the same internal structure. The major difference is in their length.\xa0Cilia\xa0and\xa0flagella\xa0move because of the interactions of a set of microtubules inside.
