Few organisms can survive at this temperature. What adaptations might archaea possess that allow them to survive in such extreme heat?arrow_forward
- What effect did the events describe endosymbiotic theory have on eukaryotic energy production?arrow_forwardWhy is it very important for us to understand the diversity of prokaryotic organisms since we cannot see them with our naked eyes? What could be the implications if we neglect these organisms and let them be a nuisance topic in Biology?arrow_forwardCyanobacteria was responsible for the increase in oxygen levels billions of years ago. They play a decisive role in changing the earth’s environment. Explain how are Cyanobacteria related in changing the early earth’s environment which later suitable for the development of other organisms.arrow_forward
- Why are prokaryotes so abundant and have such high diversity?arrow_forwardFossil evidence indicates that prokaryotes have been around for about 3.5 billion years, whereas the origin of eukaryotes has been dated at only about 1.5 billion years ago. Suggest why, in spite of the lesser time for evolution, eukaryotes are much more diverse (have a much larger number of species) than prokaryotes.arrow_forwardDiscuss the Endosymbiotic Theory. Do you think it is a strong explanation on how the eukaryotes emerged on Earth?arrow_forward
- Why are archaebacteria called living fossils?arrow_forwardin 1967, Lynn Margulis developed the endosymbiotic theory. As seen in the diagram below, the endosymbiotic theory describes how over thousands of years, free-living prokaryotes formed living communities inside larger ancestral prokaryotic cells. Today, we identify those early free-living prokaryotes as the mitochondria, chioroplasts, and possibly other organelles. Endesymbietic Theery How did the development of Margulis' theory aid in our understanding of how complex organisms came into existence? A. It provided an explanation as to why prokaryotic cells do not have a nucdeus. B. It provides an explanation as to why bacteria and mitochondria are similar in size. C. It provides an explanation of how life today could have originated from a single cell. D. It provides an explanation of how prokaryotic and eukaryotic cells use oxygen to work.arrow_forwardArchaea are often found living in extreme conditions of heat, salt, and acidity, which are similar to those found in early earth. Speculate on the origin of life, especially as it relates to the archaea.arrow_forward
