| 1 | Which of the following changes might cause algal toxin levels to fluctuate? |
 | A) | Exposure to sun |
| B) | Water depth |
| C) | Minerals available |
| D) | Temperatures |
| E) | All of the above could cause algal toxin levels to fluctuate |
|
| 2 | The following is a description of which type of algae?
They spin as they are propelled forward. They possess two flagella, each of which rests within a groove encircling the organism. When moving, the longitudinal flagellum extends behind the cell propelling it forward, while the transverse flagellum beats within its groove and spins the cell. |
| A) | Rhodophyceae |
| B) | Alveolata (Dinoflagellates) |
| C) | Synurales |
| D) | Xanthophyceae (Yellow-Green Algae) |
| E) | Chrysophyceae: The Golden-Brown Algae |
|
| 3 | Algal blooms often occur when which nutrients accumulate in the water? |
| A) | Mercury and sulfur |
| B) | Potassium and sodium |
| C) | Copper and iron |
| D) | Phosphorous and nitrogen |
|
| 4 | Categorization of algae is challenging. In the hybrid system of algal classification, what are the categories of algae based on? |
| A) | The type of photosynthetic pigments present, the chemical makeup of the cell wall, cellular morphology, the form in which food is stored |
| B) | The type of photosynthetic pigments present, genetic analysis of the DNA, cellular morphology, the form in which food is stored |
| C) | The type of photosynthetic pigments present, the chemical makeup of the cell wall, cellular morphology, the number of flagella |
| D) | The type of photosynthetic pigments present, the chemical makeup of the cell wall, the physical habitat of the algae, the form in which food is stored |
|
| 5 | Which of the folllowing choices describes the similarities between members of the group Chlorophyta/Chloroplastida and land plants? |
| A) | They store energy from photosynthesis as starch, most species in this group have cell walls made of chitin, and similar to plants they use chlorophylls a and b for photosynthesis. |
| B) | They store energy from photosynthesis as starch, most species in this group have cell walls made of cellulose, and similar to plants they use chlorophylls a and b for photosynthesis. |
| C) | They store energy from photosynthesis as starch, most species in this group have cell walls made of cellulose, and similar to plants they use chlorophylls a and c for photosynthesis. |
| D) | They store energy from photosynthesis as oil, most species in this group have cell walls made of cellulose, and similar to plants they use chlorophylls a and b for photosynthesis. |
