- The prtists that causes malaria evolved from a photosynthetic ancestor and has the remnant of a chloroplast. The organelle no longer functions in photosynthesis, but it remains essential to the protist. Why might targeting this organelle yield an antimalarial drug that produces minimal side effects in humans?Dinoflagellates 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…Dinoflagellates are unicellular, marine protists. Dinoflagellates are bioluminescent, but only at night.

- 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?Which parasitic protist evades the host immune system by altering its surface proteins with each generation? a. Paramecium caudatum b. Trypanosoma brucci c. Plasmodium falciparum d. Phytophthora infrstansThe presence of a contractile vacuole indicates that a single-celled protist _______. a. is marine c. is photosynthetic b. lives in fresh water d. secretes a toxin
- 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. Use this information to determine which of following protista groups is more likely to be found in a termite gut. Diatoms Radiolaria Parabasilids O Rhodophyta O Foraminifera (Forams)In secondary endosymbiosis, the plastid organelle is derived from engulfing Prokaryotic algal cell. an True FalseIn the pictures below, identify the arrowed reproductive structures of microscopic cyanobacteria based on the following descriptions: Akinetes are dormant structures larger than the vegetative cells, are rich in food reserves, and have thick walls. Most filamentous cyanobacteria develop akinetes in adverse conditions (e.g., winter, dry periods). When favorable conditions return, they germinate and produce new filaments. Hormogonia are short pieces of filaments consisting of 5–15 trichomes that fragment and develop into new filaments. Heterocytes (or heterocysts) are multicellular structures that have a thick and massive sheath, formed by members of the Nostocales. It is the location of the enzyme nitrogenase for nitrogen fixation, the conversion of nitrogen gas into ammonium and then amino acids. They may be intercalary or terminal in position and may germinate from either end or both the ends to give rise to new filaments. Non-filamentous cyanobacteria generally produce spores…
- Some molecular evidence suggests that the sister group of animals is not the choanoflagellates, but rather a group of parasitic protists, Mesomycetozoa. Given that these parasites lack collar cells, can this hypothesis be correct?
