Glycolysis takes place in the cytoplasm of most prokaryotic and all eukaryotic cells. Methanogens can be found at the bottom of the ocean, where they can create huge methane bubbles beneath the ocean floor. Many plants cannot fix their own nitrogen – meaning that they require nitrogen-fixing bacteria in the soil, or they cannot obtain the nitrogen compounds they need to live. We know that they had to be autotrophs, since they would have had to produce all of their own organic materials. Viruses are considered nonliving, but have characteristics of living and nonliving things. Chemoautotroph. Although plants perform carbon fixation in these ecosystems, many plants rely on chemoautotroph bacteria to fix nitrogen, which is necessary to make amino acids and proteins. In the industry of iron mining, research is being done into how to use these bacteria to capture and purify iron that might not otherwise be accessible to humans because it is dissolved in water or mixed with other minerals.

Is "bilateral symmetry" a pleisiomorphic or apomorphic trait in animals? Flashcards. They are considered as living because they can evolve and possess either DNA or RNA as genetic material. Because they obtain their energy from iron, they can live in water with iron concentrations that would kill most organisms. Without chemoautotrophs, life would only be able to exist where energy could be derived from sunlight. C. Viruses are considered nonliving as they don't metabolize or grow and depend on their host cells to replicate. Chemoautotroph. They are no longer autotrophs, as they are no longer able to feed themselves. What is the embryonic origin of these cells? We have no fossils of the first cells on Earth, so we are not able to say at this time what they were like.
