Do flagella and cilia use ATP?

Motion of cilia and flagella is created by the microtubules sliding past one another. This requires: motor molecules of dynein, which link adjacent microtubules together, and. the energy of ATP.

So, what differences are there between cilia and flagella?

Cilia are short and there are usually many (hundreds) cilia per cell. On the other hand, flagella are longer and there are fewer flagella per cell (usually one to eight). Though eukaryotic flagella and motile cilia are structurally identical, the beating pattern of the two organelles can be different.

Are cilia and flagella organelles?

The evolution of eukaryotic cilia and flagella as motile and sensory organelles. Eukaryotic cilia and flagella are motile organelles built on a scaffold of doublet microtubules and powered by dynein ATPase motors.
