Textbook Question
Chapter 12, Problem 1A
Alexandrium (red tide) has been called a plant Protest, Protozoan and alga in the past. Now it’s in the Kingdom Chromalveolata, along With Plasmodium and Paramecium. Are all Chromalveolata photosynthetic? Are any? Explain why it has been so difficult to accurately classify Alexandrium.

Apicomplexans evolved from a photosynthetic ancestor and have the remnant of a chloroplast. This organelle no longer acts in photosynthesis, but remains essential to the protist. Why might targeting this organelle yield an antimalarial drug with minimal side effects in humans?
Polysiphonia is characterized to have a triphasic type of life cycle. Triphasic is one of the four types of life cycle generally exhibited by algae. The other types are haplontic, diplontic and diplohaplontic. Describe each life cycle and diagram the stages to differentiate one from the other. Give examples of algae that exhibits them.
Which of the following is least well characterized as an alga?

- Why are red algae red? What distinguishes plasmodial and cellular slime molds? What are the ecological roles of protists? Why are photosynthetic protists so important to marine/aquatic ecosystems? What limits the growth of these organisms and what causes blooms? What will be affected if marine producers are disrupted?arrow_forwardDinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night. During the day, they carry out photosynthesis similar to other autotrophs. At night, however, they bioluminesce every time they are disturbed. They are often seen in the wakes of ships at night. While the reason for this bioluminescence is not fully understood, many scientists concur that it is a form of self-defense. If small fish begin to feed upon the protists, the protists will begin to bioluminesce. These flashes of light in the dark water can alert larger fish and draw them towards the small fish, upon which they prey. By making the small fish vulnerable, the dinoflagellates are able to protect themselves. Based on the information above, a researcher decides to design an experiment in which she is testing how long it takes for dinoflagellates to recover after different amounts of disturbance. She maintains 10 containers of dinoflagellates with similar temperature, salinity and…arrow_forwardDinoflagellates are unicellular, marine protists.

- The termite gut environment is lacking a fresh supply of oxygen O2. However, it is rich with food due to the presence of bacteria that contain enzymes capable of breaking down cellulose and lignin, the macromolecules that make wood.
