1. Cilia and Flagella
By Morgan Brady

2. Evolution Centrioles produce basal bodies Basal body in the cytoplasm
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 Multi-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

4. Paramecium - Locomotion
Paramecium
- Locomotion

5. Human respiratory tract - Move mucous and debris
Human respiratory tract
- Move mucous and debris

6. Where are they found? Cilia Flagella 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
