“Watermelon snow” in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high-altitude year-round snowfields. In both locations, UV light levels tend to be high. Based on what you learned in this chapter, propose an explanation for why this photosynthetic alga appears reddish-pink.

1. Explain the differences between cilia and flagella noting the length and abundance of each. How do these differences contribute to the varied motility of each group?
2. Think about the two different trophic mechanisms of each group (mixotrophy vs heterotrophy). How do you think cilia and flagella are related to trophic mechanisms of these two groups?

- "Watermelon snow" in Antarctica is caused by a species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis). These algae are also found in high altitude in year-round snowfields. In both locations, UV light levels tend to be high. The reddish-pink color of these algae is due to the presence of carotenoid pigments, which absorb blue light while reflecting red light. Those pigments protect the chloroplast from ultraviolet radiation, as well as absorbing heat, which provides the algae with liquid water as the snow melts around it. This molecular variation in plants illustrates a relative fitness because the molecular adaptations in chlorophyll pigments have passed to the next generation b innate variability because plants have evolved molecular differences to an environmental stimuli c unselective adaptation because plants have evolved molecular differences to adapt to different wavelengths of light d inclusive…arrow_forwardThe main product of fossil fuel combustion is CO2 , and thisis the source of the increase in atmospheric CO2 concentration.

- Turbidity affects light penetration. Discuss how this impacts the growth and reproduction of the algae and cyanobacteriaarrow_forwardCompare photo litho autotrophy with chemo-organo heterotrophy. Sun light is the ultimate source of energy and all living organisms obtain their energy directly or indirectly from the sun. However in deep-sea vents (where there is no sun light) life has originated and the many groups of microorganisms are flourishing in such environment. How? Explain your reasoningarrow_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_forward

What type of microscopy (brightfield, darkfield, or phase contrast) was to obtain the image? Explain how you can tell. b. Name a different type of microscopy would be also appropriate to use to visualize the organism in the image. How would the image change if you used that type of microscopy instead? 7.
