Chapter 3, Problem 9TMW
Summary Introduction
To determine:
The reason that some scientists consider that archaea is more closely related to eukaryotes than they are to the other prokaryotes.
Introduction:
Archaea share some common features with bacteria such as presence of 70S ribosomes, fibrous cytoskeleton, circular DNA, and lack of membranous organelles but they both differ on the basis of cytoplasm.

- In the domain system of classification, prokaryotes are divided into two domains: Bacteria and Archaea. The two domains differ in all BUT one feature. Which feature do they have in common? Question options: They both have identical cell walls. They both have prokaryotic cells. They both thrive in extreme environments. They both are able to live only under anaerobic conditions.arrow_forwardArchaea are so named because option1-their cell structure is thought to be more primitive than the cell structure of bacteria option2-they arose from the joining of members from the Archaea and Bacteria Domains. option3-many survive in extreme conditions thought to be similar to ancient earth option4-they are thought to be the first group of prokaryotes to evolve on eartharrow_forwardSome prokaryotes, especially archaea, are capable of living in extreme environments, such as deep-sea vents, where temperatures can reach 80°C (176°F). Few organisms can survive at this temperature. What adaptations might archaea possess that allow them to survive in such extreme heat?arrow_forward
- Despite many interesting characteristics and features observed in Archaea, why is there not much study about these organisms?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_forwardIf you visit a lake in the middle of the Amazon and take water samples to analyze under a microscope from a nearby university that has good instrumentation and there you detect microorganisms that are not visible to the naked eye. What studies would you do to determine if they are bacteria, archaea, fungi or protozoa? Explain each type of analysis and how would you rule out members of each group? Write at least 3 paragraphsarrow_forward
- How do bacteria and archaea differ from each other? Contrast prokaryotic cells with eukaryotic cells.arrow_forwardWhat are the flaws ? Prokaryotes can live in many different environments. Anerobic organisms need oxygen to survive, while aerobic organisms can survive without oxygen. Autotrophs are organisms that can assemble high energy macromolecules for their energy. Chemotrophs are organisms that capture energy from light. Extremophiles are organisms that grow in extreme conditions like boiling water. Gram-positive bacteria have few layers of peptidoglycan, while gram-negative bacteria have many layers of peptidoglycan and are surrounded by an outer membrane. Harmful bacteria can cause illness like food poisoning. Helpful bacteria can be used in food production to make yogurt. The endosymbiotic theory states that some of the organelles in eukaryotes were once free living prokaryotes. This is supported by the mitochondria and cytoplasm since they have their own DNA and ribosomes. Harmful protists can cause diseases like malaria in humans and downy mildew in plants. Helpful protists can be…arrow_forwardWhich of the following statements concerning prokaryotes is TRUE? They have no nucleus and hence no DNA They have no Golgi apparatus They include bacteria, yeast, and protozoans They are all able to live on inorganic energy sources Both (b) and (c) are correctarrow_forward
- Archaea are often described as chimeric organisms having some features that are similar to bacteria and some that are similar to eukaryotes. Based on what you have just read in this section, provide two examples that illustrate the similarity of archaea (explain them) to bacteria; list and describe two examples of their similarity to eukaryotesarrow_forwardWhy do microbiologists believe that the Archaea were the type of microbes from which all other life descended?arrow_forwardGlycerol-3-phosphate lipids are found in the cell membranes of which prokaryotic kingdom? kingdom Archaeobacteria kingdom Animalia kingdom Fungi kingdom Plantae kingdom Eubacteriaarrow_forward
