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.

Which of the following are generally viewed as evidence that mitochondria and chloroplasts are derived from single celled organisms (select all that apply)? Both miochondria and chloroplasts divide autonomously using a mechanism that resembles binary fission Mitochondrial and chloroplast genomes both exhibit sequence similarity to extant single celled organisms Mitochondria and chloroplasts are both capable of persisting indefinitely outside of eukaryotic cells Both mitochondria and chloroplasts have their own circular genomes

4. Development of organelles Aa Aa 3 Modern eukaryotic cells are very complex and have many features that allow them to function efficiently. These complexities took a very, very long time to evolve and likely progressed as a series of small improvements that were naturally selected. For example, modern eukaryotic cells have internal membranes surrounding their organelles and the nucleus. This arrangement likely arose when the cellular membranes of some ancient bacterial cells accidentally folded to become internal membranes. Which...

Question 7 0.3 pts The chloroplast is a membrane-bound organelle very similar to the mitochondrion. Both organelles are thought to have been acquired through an endosymbiotic event where a bacterium was engulfed by an ancestral eukaryotic cell and accidentally retained over evolutionary time and evolved into specialized organelles. Which area of the chloroplast is most similar to the inner membrane of the mitochondria such that both areas in...
