- Which of the following statements supports the concept of the endosymbiotic theory? A. Proteins may be trafficked within the endomembrane system. B. Ribosomes are present in the cytoplasm of prokaryotic cells and eukaryotic cells. C. Chloroplasts have many features in common with bacteria. D. Mitochondria can fuse together to form larger organelles within eukaryotic cells.arrow_forwardAccording 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.arrow_forward1) According to the endosymbiotic theory of the origin of chloroplasts, photosynthetic prokaryotic cells________? 2) The tremendous increase in the diversity of animals beginning about 542 million years ago is called the______? 3) Two completely unrelated species that are found in the same environment are observed to have the same adaptation.

Those cells would duplicate comparisons shown elsewhere in the matrix. C. Those comparisons were not made by the researchers.arrow_forwardWhy do scientists believe that mitochondria evolved before chloroplasts? A. because all eukaryotic cells have mitochondria but not all eukaryotic cells have chloroplasts B. because mitochondria are more efficient than chloroplasts C. because mitochondria live longer than chloroplasts D. because mitochondria are larger and stronger than chloroplasts Chrome OS Wienarrow_forwardOne 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.
