No, algae are not cilia.
Algae possess structures called flagella, which are sometimes mistaken for cilia. However, there are key differences between the two:
- Flagella vs. Cilia: Algae have two mobile hairs that are called flagella, not cilia.
- Movement: Algae flagella exhibit a much different movement pattern compared to cilia. Instead of swaying back and forth, they spin around and beat the water almost similar to a rotor. Cilia, on the other hand, move in a coordinated, wave-like motion.
| Feature | Cilia | Flagella |
|---|---|---|
| Presence in Algae | No | Yes |
| Movement | Wave-like, back and forth | Rotational, like a rotor |
| Function | Movement, sweeping substances | Movement |
