Answer

Cilia and flagella are both involved in movement. Cilia propels substances across the cell’s surface, and the flagella propels the entire cell. The lack of dynein would render these two structures dysfunctional. Without Cilia to “sweep out” the respiratory tract, the lining of this system would be lost, which would then lead to increased respiratory problems. The loss of a functioning flagellum would render the sperm immobile (not able to move) and lead to sterility (unable to produce children) in males.
