According to the endosymbiosis theory, chloroplasts and mitochondria are derived from bacteria that took up residence within eukaryotic cells. At one time, prior to being taken up by eukaryotic cells, these bacteria were free-living organisms. However, we cannot take a chloroplast or mitochondrion out of a living eukaryotic cell and get it to survive and replicate on its own. Why not?

What is the endosymbiotic theory as it relates to the cellular organelles, mitochondria & chloroplasts, found in eukaryotic cells? There have been several different characters throughout the years that have served as Batman’s sidekick under the codename ‘Robin’. Name as many as you can: The resolution of a microscope (commonly abbreviated as D) is way to objectively describe the magnification ability. As resolution increases by changing objective lens, what happens to depth of field? What is the relationship between magnification,...

Which of the following statements about the endosymbiotic theory is false? Which of the following statements about the endosymbiotic theory is false? The entire genome of the ancestral bacteria has been preserved in present-day mitochondria and chloroplasts. The ancestral bacteria, from which mitochondria and chloroplasts are derived, were capable of photosynthesis and aerobic respiration. Mitochondria and chloroplasts arose independently from free-living bacteria. Eukaryotic cells engulfed the ancestral bacteria from which mitochondria and chloroplasts are derived, and the two entities formed...

20. Rere to the which shows the phylogenetic tree of major groups of living organisms. Based on the figure, which statement about the endosymbiotic origin of eukaryotic mitochondria is true? Some prokaryotic archaea possess mitochondria. Mitochondria are derived from endosymbiotic bacteria. Bacteria is more closely related to Eukarya than to Archaea. Mammals possess chloroplasts, which become functional during starvation. The common ancestor of Archaea and Eukarya possessed mitochondria.

Which of the following statements does NOT provide evidence in support of the endosymbiotic origin of eukaryotic cells? a. The DNA sequence of mitochondria is similar to the DNA sequence of respiring bacteria. b. The DNA of chloroplasts is circular like the DNA of phototrophic bacteria. c. Mitochondria are capable of free-living outside of a eukaryotic cell. d. There is a lot of sequence homology between the DNA sequences of chloroplasts and phototrophic bacteria.

5. Mitochondria and chloroplasts were once free-living bacteria that later migrated into eukaryotic cells. Mitochondria make energy while chloroplasts prepare their own food. a) If Gregor Mendel were a molecular biologist and laid his hands on a free-living mitochondrion, would he have got his 3:1 ratio crossing two mitochondria? b) In its free-living condition, can a chloroplast code for proteins, and if yes, what are the two most important enzymes that aid in its survival? c) After endosymbiosis, what happenned...
