Solved in 3 steps
- How can the hypothesis that asserts that chloroplasts as well as mitochondria were primitive prokaryotes that associated in mutualism with primitive anaerobic eukaryotic cells be corroborated?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?The amoeba Pelomyxa palustris is a single-celled eukaryote with nomitochondria, but it contains symbiotic bacteria that can live in thepresence of oxygen. How does this observation support theendosymbiont theory?
- What phylogenetic and physiological evidence suggests thattoday’s hyperthermophiles are the closest living links to Earth’searliest cells?What evidence supports the idea that the mitochondrion andchloroplast were once free-living members of the domainBacteria?Suppose you isolated a bacterial strain that carried out oxygenic photosynthesis. What photosystems would it possess, and what group of bacteria would it most likely belong to?
- Compare CO2 fixation in anammox bacteria and purple sulfurbacteria. What characteristics do these processes share and howare they different?Besides 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?compare and contrast chloroplastss and mitochonndria from teh perspective of : organization of their electron transportation systems (z-scheme versus ETC)
