Textbook Question
Chapter 3, Problem 3AWK
Mitochondria resemble a bacterial cell in a number of ways. Some scientists hypothesize that mitochondria evolved from aerobic prokaryotes that were engulfed by anaerobic eukaryotes, and now both have evolved together in a mutually advantageous way. Can you think of an explanation for why it might have been advantageous for both cells to enter into such an arrangement?

- The fossil record suggests that the first cells were prokaryotes; scientists believe that eukaryotic cells evolved from prokaryotic cells in a particular manner; this theory is called endosymbiotic theory. Explain,in your own words what is meant by the endosymbiotic theory How does the structure of mitochondria and chloroplasts support the endosymbiotic theory ? asap please.arrow_forwardHow did the development of Margulis' theory aid in our understanding of how complex organisms came into existencearrow_forwardThe endosymbiotic theory argues that prokaryotes become some of the organelles of early eukaryotic cells. All of the following support this hypothesis Except: A. The mitochondria and chloroplasts have their own DNA and are nearly idential to some free-living prokaryotes b. Mitochondria and chloroplasts are nearly idential to some free-living prokaryotes. c. Mitochondria and chloroplasts have their own DNA d. The vacuoles can come and go across the plasma membranearrow_forward
- Paramecia live mostly in freshwater and move with the use of structures called cilia. They utilize contractile vacuoles to expel water that enters the cell by osmosis. Euglena are unicellular organisms that use flagella for movement and chloroplasts for photosynthesis. They are found in freshwater and saltwater. Scientists have determined that Paramecia and Euglena are eukaryotes and not prokaryotes because they havearrow_forwardMitochondria and Earth’s higher concentration of atmospheric oxygen allowed early eukaryotes to evolve in size and complexity – to become larger and do more cellular work. Using your understanding of cellular respiration and the role of oxygen in the electron transport chain, discuss how endosymbiosis, and the evolution of mitochondria, was a critical factor in affecting cell size and how much work, i.e., metabolism, the cell can perform.arrow_forwardBelow are three statements - two of which are truths and one is a lie. Which of the following statements is a lie? Select one: a. Although both prokaryotes and eukaryotes have a plasma membrane that protects them from their surrounding, many of the extremophiles are prokaryotic and only a few are eukaryotic. b. Despite different in appearance, nerve and muscles cell have the same genetic material and the same ability to produce electrochemical impulses. c. Although very few in numbers, there are special prokaryotes that have a membrane-bound nucleus.arrow_forward
- For what reasons would a eukaryotic cell evolve an endoplasmicreticulum and a Golgi apparatus?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_forward1) Discuss several characteristics of mitochondria and chloroplasts that lend evidence to the endosymbiotic theory. As stated in the text, this theory may explain the origin of these organelles. Can this theory explain the origin of the ER?arrow_forward
- Considering which organelles were created through the endosymbiotic theory, which of the following is NOT something that the host could receive from the engulfing a symbiont? A. the engulfed cell provided the host cell with adenosine triphosphate (ATP) B. the host cell was able to survive anaerobic conditions with the engulfed cell alive C. the engulfed cell provided the host cell with carbon dioxide D. the engulfed cell allowed the host cell to metabolize glucosearrow_forwardWhich statement regarding mitochondria is true? Group of answer choices Mitochondria are semi-autonomous which means they can move, make proteins, and divide. Mitochondria are used to recharge ADP into ATP. Scientists theorize that mitochondria were once free-living alpha proteobacteria because mitochondria possess two membranes, bacterial genes, and a bacteria-like chromosome. All previous answers None of these answersarrow_forwardWe know that bacteria and archaea are very diverse in their metabolic capabilities, such as the consumption of organic waste and carbon dioxide and the creation of others such as oxygen, alcohol, methane, nitrates, and antibiotics. Amazingly these known capabilities only come form the 1-10% of prokaryotes that have been identified. Scientists hypothesize that at least 90% are undiscovered and have potential metabolic capabilities we could harness to benefit human life. If you were a scientist, what metabolic capability of bacteria would you try to discover to solve a human or environmental problem? Why?arrow_forward
