Century Dictionary and Cyclopedia
    • flagellata A primary group of Infusoria, as distinguished from the Tentaculifera, or Acinetæ, and from the Ciliata. They are minute organisms of monadiform structure and character, provided not with cilia proper or with tentacles, but with a long whip-like flagellum, or with two or more flagella, which may be situated together at one end of the body, or be widely separated. There are generally an endoplast and a contractile vacuole, but no permanent oral aperture, though there is an oral region of the body constituting the food-vacuole, by which food enters along with a globule of water. The flagella are locomotory organs. The cell of which a flagellate infusorian mainly consists differs much in form in the different genera, being sometimes prolonged around the base of the flagellum like a collar, and the whole animal may have a calycine investment. The flagella of the same animal may differ much, one being stout and only occasionally moved, the other forming a delicate cilium in constant vibration. The Flagellata multiply by various methods of fission and sporulation, and also by conjugation. Also called Mastiguphora.
