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

- Compare 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_forwardBesides adaptation to low light intensities, are there any other adaptations in the photosynthetic pigments found in bacteria that live in the vicinity of deep-ocean thermal vents?arrow_forwardAs with plant adaptations againstherbivores, other biological processes can involve multiple levelsof biological organization (Figure 1.3). Discuss examples ofspecialized photosynthetic adaptations involving modificationsat the molecular (Concept 10.4), tissue (Concept 36.4), andorganismal (Concept 36.1) levels.arrow_forward
- A scientist claims that the Presence of aquaporins is in chloroplast membrane support that Endosymbiotic theory?arrow_forward“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.arrow_forwardIn a shallow coastal ecosystem dominated by seagrasses, nutrient limit primary production under low nutrient ( oligrtropihc) conditions while light becomes the limiting factor under high nutrient ( eutrophic) condition. In the conceptual model given explain why sea grasses, macroalgae and poluplantkon are in the position of the graph. Kindly explain your answerarrow_forward
- EVOLUTION CONNECTION Photorespiration can decreasesoybeans’ photosynthetic output by about 50%. Would youexpect this figure to be higher or lower in wild relatives ofsoybeans? Why?arrow_forwardcompare and contrast chloroplastss and mitochonndria from teh perspective of : organization of their electron transportation systems (z-scheme versus ETC)arrow_forwardplease choose correct letter and explain why you choose it 1. As a percentage of the flora, in which of the following geographic locations would the highest percentage of C3 plants be expected? a. Canada b. Brazil c. Colombia d. Venezuela e. USA 2. Which of the following statements describes what cyclic and non-cyclic electron transport in chloroplasts have in common? a. They produce ATP. b. They produce NADPH. c. They both involve photosystem I and photosystem II. d. They produce both ATP and NADPH. e. They both use photosystem II only. 3. Which of the following statements describes what fluorescence and bioluminescence have in common? a. ATP provides the energy for both processes. b. Light provides the energy for both processes. c. Light is produced by a pigment in both processes. d. Both processes emit light. e. All of the abovearrow_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_forwardAnimal cells have neither cell walls nor chloro-plasts, whereas plant cells have both. Fungal cells aresomewhere in between; they have cell walls but lack chlo-roplasts. Are fungal cells more likely to be animal cells thatgained the ability to make cell walls, or plant cells that losttheir chloroplasts? This question represented a difficultissue for early investigators who sought to assign evolu-tionary relationships based solely on cell characteristicsand morphology. How do you suppose that this questionwas eventually decided?arrow_forwardCoral reefs, bleaching, and climate change Where are the dinoflagellates located inside the coral polyp? What part of the dinoflagellate (the algae) is actually damaged by excess energy When stimulated by too much energy (light or heat), what does the algae begin to produce? And how does this product impact the coral poly? Why is bleaching so detrimental to the coral animal itself? Why is bleaching damaging to the entire reef ecosystem?arrow_forward
