  1. Cilia and Flagella By Morgan Brady

  2. Evolution • Centrioles produce basal bodies • Ex: the development of sperm cells • Basal body in the cytoplasm • Cilia and Flagella grow • Remains attached to it • Production is continued

  3. Function • Single-celled organisms • Locomotion • Ex: sperms swimming • Multi-celled organisms • Move cells • Transports fluid or materials past cells • Ex: respiratory tract in humans • Generates water currents to carry food

  6. Where are they found? • Cilia • Animal cells (some) • Protist cells • Prokaryotes • Flagella • Animal cells (some) • Prokaryotes • Plant cells (some)

  7. Structure • Cilia: great numbers • Flagella: solitary • Hair- like • Contain cytoplasm • Enclosed by the plasma membrane • 9+2 arrangement

  9. Movement • Cilia • Smooth • Move almost simultaneously • Wave-like patterns of motion • Flagella • Whip-like • Breast stroke in swimming
