The concept of endosymbiosis as applied to chloroplast and mitochondria found in eukaryotes: a) is based on evidence that Chloroplasts and Mitochondria were originally prokaryotes, b) changes present day animals into plants, c) explains how chemical evolution caused the appearance of life, d) allowed chloroplasts to carry out aerobic metabolism, e) all are true.
Mitochondria are thought to be the descendants of certain alpha proteobacteria. They are, however, no longer able to lead independent lives because most genes originally present in their genome have moved to the nuclear genome. Which phenomenon accounts for the movement of these genes? Group of answer choices A. recombination B. conjugation C. translation D. endosymbiosis
One piece of supporting evidence for the endosymbiotic theory for the origin of eukaryotic cells is thata. eukaryotic cells have internal membranes.b. mitochondria and chloroplasts have their own DNA.c. Golgi bodies and endoplasmic reticulum were present in ancestral cells.d. the nuclear membrane could only have come from another cell.
For each of the following indicate if they evolved once, twice, or perhaps several times. a) acquisition of mitochondria b) acquisition of chloroplast c) multicellularity d) origin of ribosomes
Describe the Theory of Endosymbiosis. a) Briefly define the Endosymbiotic Theory. 2 pts,b) Explain why the Theory of Endosymbiosis is considered a “theory” and not a “hypothesis.” 3 pts,c) Provide a description of eukaryotic and prokaryotic cells, including at least 4 similarities and 4 structural differences. 4 pts,d) Describe the sequence of events with anaerobic ancestral proto-eukaryotes and aerobic prokaryotes that led to the formation of mitochondria and chloroplasts inside eukaryotic cells. (Be sure to define aerobic and anaerobic respiration.) 6 pts,e) Explain how each, the anaerobic ancestral proto-eukaryotes and aerobic prokaryotes, benefited from the relationship. 4 pts,f) Describe 7 pieces of evidence for this scientific theory. Some of this evidence will consist of a list of similarities between mitochondria characteristics and bacteria characteristics. Along with this list of similarities, explain HOW the characteristics are similar. 10 pts,g) The Endosymbiotic Theory…
The extra energy required for the evolution of the highly complex eukaryotic cell was possible because: a) mesosomes released enzymes into the nucleus b) two types of prokaryotic bacteria became endo symbiotic invaders of the complex cells c) the DNA of the eukaryote cell functions within the nucleoid area d) chloroplasts were able to use O2 to conduct photosynthesis e) the space between the two layers of the nuclear membrane contained mitochondria
Identify which of the following statements is false and correct the statement. a. Brown and red algae are not closely related phylogenetically. b. Chloroplasts in brown and red algae are monophyletic. c. Brown algae gained chloroplasts by engulfing green algae (endosymbiosis). d. None of the statements are false.
Which of the following observations about a bacterium would distinguish it from the last eukaryotic common ancestor? a. A double-stranded DNA genome b. Lack of a membrane-bound structure surrounding the genome c. Fatty acids in the lipid bilayer of the plasma membrane d. Enclosed by a cell wall
A. Classify the organisms (A-D) based on their oxygen requirements. Name one location where you are most likely to encounter these organisms (1 location/organism).B. Organism C could not grow in the presence of oxygen. Explain the molecular reason behind this observation (What affect did oxygen have on C that caused it not grow)? C. Your friend repeats the above experiment in Question1 and observes growth of all 4 organisms on both plates. Provide an explanation for her results. (You may assume that your results are correct, since you have repeated the experiment several times and gotten the same results).
