Flagellar movement of the Sessile Flagellates Actinomonas, Codonosiga, Monas, and Poteriodendron

摘要: Summary Water currents set up by flagellar activity are used to bring food particles the body in each of sessile flagellates Actinomonas, Codonosiga, Monas, and Poteriodendron. The water produced 4 organisms all somewhat different, and, while that Codonosiga is expected direction with flow from base towards tip, other 3 forms tip base.
