According to the theory of endosymbiosis, organelles, like mitochondria and chloroplasts, were once free-living cells that were absorbed into another cell. The relationship benefited both cells to stay together. What evidence do scientists observe today that supports the theory of endosymbiosis? Select all that apply.   a There are ribosomes found inside mitochondria and chloroplasts just like there are inside cells. b Looking inside mitochondria and chloroplasts, one will find that they each contain their own DNA. c Mitochondria and chloroplasts are found inside all cell types. d Mitochondria and chloroplasts each have a membrane around them just like a cell would.
The 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 membrane
Which of the following is NOT evidence for endosymbiosis? A. Bacteria and mitochondria both have nuclei. B. Bacteria and mitochondria both have ribosomes. C. Bacteria and mitochondria both have circular DNA. OD. Bacteria and mitochondria both reproduce via binary fission E. Bacteria and mitochondria both have membranes.
