15 Points Per Correct Answer - No time limit  

1. There are three types of protists, one of which is animal-like. What is the term used to describe the animal-like protists? none of these algae protozoans amoebas

2. The other two types of protists are plant-like and fungi-like. Although fungi-like protists do not have a term to describe them, what is the term used to characterize plant-like protists? algae euglenoids phytoplanktons none of these

3. There are four ways in which a protozoan can move. They can either move by using flagella, cilia, spores, or pseudopodia. What are pseudopodia? cytoplasm containing extensions a long whiplike structure an organelle that collects and pumps out excess water a short hairlike fiber

4. There are four main groups of protozoans: amoebas, flagellates, ciliates, and sporozoans. Plasmodium is a type of sporozoan that causes a disease. Which disease does plasmodium cause? small pox malaria cancer none of these

5. Green algae alternate between living as a haploid organism, which is an organism with only one set of chromosomes, and a diploid organism, which is an organism with two sets of chromosomes. What is the term used to describe the haploid form of an organism? sporophyte thallus pellicle gametophyte

6. There are three categories of fungi-like protists. Water molds make up the first category. What makes up the other two categories?(Hint: One answer applies to both.) none of these downy mildews slime molds sear mildews

7. Slime molds vary in color and live in cool, moist, shady places. There are two types of slime molds. One type of slime molds is plasmodial slime molds. The other type is cellular slime molds. True False

8. Slime molds are also similar to another type of protist. This is because the life cycles and methods of obtaining food for both slime molds and protists are similar. What other type of protists are slime molds compared to? algae protozoan water molds none of these

9. Water molds have a white, fuzzy appearance. They are similar to fungi because of the way in which they obtain food, but are classified as protists. Why are water molds classified as protists instead of fungi? water molds cause disease in plants water molds produce flagellated reproductive cells water molds grow on decaying matter water molds remain haploid during their life cycle

10. There is little evidence to prove where protists originated from, but biologists are currently testing DNA and RNA to find an answer. However, biologists do agree on the ancestry of one group of protists. What do biologists say originated from ancient green algae? modern plants mushrooms bacteria none of these
