Question
Chapter 16, Problem 16TYK
Summary Introduction
To explain:
The feasibility of the approach of using a supertanker of iron dust in the oceans to grow more algae.
Introduction:
The growth of algae in the Southern Ocean was achieved by depositing huge reserves of metal iron on the ocean surface. The algae utilize carbon dioxide and help in the process of photosynthesis by consuming carbon dioxide. The decrease in the levels of the carbon dioxide decreases the chance of global warming.

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 this week, propose an explanation for why this photosynthetic alga appears reddish-pink.
In addition to the pigments commonly associated with photosynthesis, a certain photosynthetic species contains two additional pigment types. Which of the following best supports the claim that this species is better adapted to environmental changes than other photosynthetic species are?
a) The additional pigments allow the species to outcompete other species for the wavelengths of light commonly used in photosynthesis.
b) The increased pigment concentration better facilitates energy production within the cells of the species.
c) The pigment combination allows the organism to absorb heat as well as light, making better use of available energy.
d) The additional pigments allow the species containing them to harvest energy from wavelengths of light that the other photosynthetic species cannot use.
“Watermelon snow” in Antarctica is caused by a certain species of photosynthetic green algae that thrives in subzero temperatures (Chlamydomonas nivalis).

- Explain wellarrow_forward"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 genus Ferroplasma consists of a few species of acid-loving archaea. One species, F. acidarmanus, was discovered to be the main component of slime streamers (a type of biofilm) deep inside an abandoned California copper mine (Figure 4.11A). F. acidarmanus cells use an ancient energy-harvesting pathway that combines oxygen with ironsulfur compounds in minerals such as pyrite. This reaction dissolves the minerals, so groundwater that seeps into the mine ends up with extremely high concentrations of metal ions such as copper, zinc, cadmium, and arsenic. The reaction also produces sulfuric acid, which lowers the pH of the water around the cells to zero. Despite living in an environment with a composition similar to hot battery acid, F. acidarmanus cells maintain their internal pH at a cozy 5.0. Thus, researchers investigating Ferroplasma metabolic enzymes were surprised to discover that most of the cells enzymes function best at very low pH (Figure 4.11B). A. Deep inside one of the most toxic sites in the United States: Iron Mountain Mine, in California. The water in this stream, which is about 1 meter (3 feet) wide in this photo, is hot (around 40C, or 104F), heavily laden with arsenic and other toxic metals, and has a pH of zero. Slime streamers growing in it are a biofilm dominated by a species of archaea, Ferroplasma acidarmanus. B. pH profiles of four enzymes isolated from F. acidarmus. Researchers had expected these enzymes to function best at the cells cytoplasmic pH (5.0). What does the dashed line signify?arrow_forward
- The common name for species like Anabena is blue-green algae. This group of bacteria are capable of photosynthesizing. Do they contain chloroplasts? Explain.arrow_forwardThe law of conservation of matter states that no matter on earth can be created or destroyed. Using the following equation: 6H2O + 6CO2 + Sunlight—> C6H12O6 + 6O2, explain how the process of photosynthesis is an example of this.arrow_forwardIn endosymbiotic theory, host cells were believed to have ingested smaller individual photosynthetic organisms through pinocytosisarrow_forward
- Why might chemosynthetic communities exist only in places like the deep-ocean floor rather than across a wide range of land and sea habitats, the way photosynthesis-based communities are?arrow_forwardIn 2010, a bew form of chlorophyll (chlorophyll f) was discovered in cyanobacteria assemblages of stromatolites growing in Shark Bay, Australia. Chlorophyll f has been isolated. and scientists are investigating the structure and function of this pigment. Based on your understanding of photosynthesis, how would you determine the wavelengths of light the pigment absorbs? How would you determine if this pigment plays a role in photosynthesis?

- “Watermelon snow” in Antarctica is caused by a certain 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. Propose an explanation for why this alga appears reddish-pink. The question is also in the picturearrow_forwardSome friends are trying to make wine in their basement. They've added yeast (which is a facultative anaerobe - it can perform both aerobic respiration and fermentation) to a sweet grape juice mixture and have allowed the yeast to grow. After several days they find that sugar levels in the grape juice have dropped, but there's no alcohol in the mixture. The most likely explanation is that the mixture needs less oxygen, because yeast only produce alcohol in the absence of oxygen the mixture needs less sugar, because high sugar concentrations prevent fermentation the mixture needs more sugar, because yeast need a lot of energy before they can begin to produce alcohol the yeast used the alcohol as a carbon source the mixture needs more oxygen, because yeast need oxygen to break down sugar and get enough energy to produce alcoholarrow_forwardWhich of the following is true about Purple Sulfur Bacteria?
