Sample multiple-choice questions: 1.
In general, how do algae and protozoans differ? a. All protozoans have cilia and all algae do not have cilia. b. Algae are free-living, and protozoans are parasitic. c. Protozoans are autotrophic, and algae are heterotrophic. d. Algae are photosynthetic, and almost all protozoans are heterotrophic. e. Algae are prokaryotes, and protozoans are eukaryotes.
2.
Groups of seaweeds can generally be distinguished on the basis of _____. a. color and the concentration of various pigments b. size c. whether they are multicellular or unicellular d. whether they have true leaves, stems, and roots e. whether they are autotrophic or heterotrophic
3.
Biochemistry can be used to identify many prokaryotes. For example, gram-positive bacteria have a cell wall composed of a thin layer of peptidoglycans that retains the purple dye, crystal violet—as a result, they stain a dark purple color. Is this statement True (a) or False (b).
Other questions may include: short-answer, matching, short-essay Other test requirements and tips: Arrive on time and prepared, yet well rested. Bring pencil, eraser, and Scantron # 882 to lecture exam.
