Anabaena  Do they have any nuclei, mitochondria, chroloplast, or ribosomes? Can you see any heterocyst? What is the function of the heterocyst? Discuss the ecology and economic importance of Anabaena?

Euglena  Describe the biology of the species, especially its mode of nutrition, reproduction, and ecology. Are all euglenas photosynthetic? Do they have any economic value? Are any harmful?

Bacillariophyta (Diatoms) What are the morphology, ecology, and economic biology of this group, especially as they relate to those of the euglenoids and dinoflagellates. What is the difference between centric and pennate diatoms? What is diatomaceous earth?

Please hand draw Euglena and lable it with the following terms: Euglena, Phylum Euglenozoa, Chloroplasts Note: Be careful not to choose Euglena cysts. Be sure to include all terms provided in the illustration.

Why might the ability to form dormant cysts be of great advantage to an agrobacterium but not as much to a rhizobium?

How would you classify this paramecium: animal-like, plant-like, or fungus-like. Why?

1. What characteristic does Euglena possess that allows it to move in its environment? 2. How are Spirogyra chloroplasts arranged in the cell?

What material makes up a large proportion of a diatom’s cell wall? What material makes up a large proportion of a diatom’s cell wall? What are flagella? What purpose do flagella serve? What do euglenoids have instead of a cell wall? What characteristics do plantlike protists share with plants? How do euglenoids obtain food when there isn’t enough light to perform photosynthesis? How do dinoflagellates compare and contrast with euglenoids? How do algae get food to live?

What is the economic importance of yeasts?
