Protists: Ciliates and Zooflagellates

The video tutorial discusses two groups of protists: ciliates and zooflagellates. Ciliates use tiny hair-like structures called cilia to move and feed, exemplified by the paramecium. Zooflagellates, on the other hand, move using a whip-like structure called a flagellum. The video highlights Giardia, a zooflagellate that can cause intestinal issues when ingested through contaminated water. It emphasizes the importance of ensuring water safety while hiking or camping.

What are cilia and what role do they play in the movement of ciliates?

Describe how the paramecium uses cilia to obtain food.

What distinguishes zooflagellates from ciliates in terms of movement?

Explain the health risks associated with Giardia and how it is transmitted.

What precautions should be taken when drinking water from natural sources?
