Locomotion
Cilia and flagella
Flagellum
9+2 arrangement of microfibrils the outer pair spiral down the flagellum
flagella are small in number and relatively large in size
pattern of contraction is sinusoidal
wave of contraction not in one plane, but in all dimensions
sometimes the flagellum is reflexed along the body with a membrane (undulating membrane) attaching it to the cell proper
flagella occur in pairs
cilia are large in number and relatively small in size
pattern of 9+2, ciliary root is associated with specilization of the outer layer of the ciliate (pellicle)
beat pattern is power and recovery, beat is metachronal
