Drew Rasmussen Matt Schmasow Biology 192 Lab January 26, 2011 C hapter 2: Kingdom Protista: Discussion Questions 1. Some algal groups belong to evolutionary lineages in the Kingdom Protista, and are therefore categorized as a protista. 2. All algae are autotrophic, and contain photosynthetic organelles. 3. Protozoans are heterotrophic and animal-like members of the kingdom Protista. 4. Protozoans is a term generally used to describe all “unicellular animals.” Protozoans are heterotrophic where most protists are autotrophic. 5. Protozoans are unicellular organisms with animal like behaviors, they are heterotrophic, but often times have plant or fungal features. 6. Virtually no ciliates cause disease, however Apicomplexans such as Plasmodium (responsible for malaria) can cause disease and can be parasites. 7. Kinetoplastids are responsible for at least 2 tropical diseases. They also have one nucleus where ciliates have two nuclei (Micronucleus and Macronucleus).

Unformatted text preview: 8. Both are heterotrophic organisms of the kingdom Protista. Foraminifera are primarily marine organisms, while Rhizopoda can live in marine water, fresh water, and soil. Foraminifera have shells with tiny projections coming out that aid in movement, and Amoebas (Phylum Rhizopoda) can have shells as well. 9. All of these organisms are capable of photosynthesis. (Euglenoids, Dinoflagellates, and Diatoms) 10. Phaeophyta, the phylum which brown algae belongs to, is responsible for large marine seaweeds. 11. Most taxa (of Brown Algae) dominate rocky shores in cooler marine areas (i.e. Coral Reefs). They are common in the intertidal zone of both Washington and Oregon. 12. Rhodophyta live in warm marine waters. 13. Slime molds are part of the Kingdom Protista because they lack the hyphae that organisms in the Kingdom Fungi have....
