Bio Quiz #2 Review - Protists and Fungi

What are the 3 major groups of protists?

• Protozoans: animal-like

• Algae: plant-like

• Molds: fungus-like

Why are protists important? (ecological roles, disease, commercial uses)

• some are used to make toothpaste (chrysophyta)

• we can eat some types of protists (e.g. nori)

• plasmodium causes malaria

Label a diagram of a Paramecium.

Label a diagram of a Euglena.

Which type of protist causes each disease (malaria, amoebic dysentery, giardiasis, toxoplasmosis)

All protozoens

• Malaria: apicomplexa

• Ameobic Dysentry: sarcodina

• Giardiasis: Zoomastigna

• Toxoplasmosis: apicomplexa

How are the protozoans classified?

By how they move

Name each Protozoan group and state how they move.

1. Zoomastigina: flagella

2. Sarcodina: pseudopodia

3. Ciliophora: cilia

4. Apicomplexa: non-motile

Why are truffles so expensive?

Why are dogs better to use when truffle hunting compared to pigs?

Pigs tend to eat the truffles once they find them.
