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 is the primary function of cilia in ciliates?

• To absorb nutrients

• To protect against predators

• To move and gather food

• To reproduce

Which protist group uses a flagellum for movement?

• Ciliates

• Sporozoans

• Zooflagellates

• Amoebas

What is a common consequence of ingesting Giardia?

• Respiratory issues

• Intestinal problems

• Skin rashes

• Headaches

Why is it important to bring your own water while hiking?

• To avoid dehydration

• To save money

• To prevent carrying extra weight

• To ensure water is free from harmful organisms

What might be misleading about the appearance of natural water sources?

• They may contain harmful organisms despite looking clean

• They are always safe to drink
