Which of the following is/are considered evidence that supports the Endosymbiotic Hypothesis that explains the origin of mitochondria and chloroplasts in eukaryotic cells? a. Mitochondria and chloroplasts have more than one membrane surrounding them b. Mitochondria and chloroplasts divide via binary fission on a different schedule than the rest of the cell c. Mitochondria and chloroplasts possess DNA unique from the rest of the cell d. The morphology of mitochondria and chloroplasts is similar to the morphology of certain prokaryotic organisms

Which of the following count as evidence for the endosymbiotic origin of mitochondria and chloroplasts? Beta-barrel proteins are present in the outer membranes of mitochondria, chloroplasts, and bacteria. Mitochondria and chloroplasts are distinct from the endomembrane system and cannot be synthesized de novo (from nothing). Mitochondria and chloroplasts contain their own genomes. Mitochondria and chloroplasts have bacteria-like ribosomes. When phylogenetic trees are reconstructed, mitochondria and chloroplasts branch near archaea.

Which of the following BEST describes evidence for the endosymbiotic origin of the eukaryotic cell? presence of chloroplasts in all organisms presence of mitochondria in all organisms fossilized specimens mitochondria and chloroplasts possess their own, circular DNA the first eukaryotic cell was based on RNA rather than DNA as hereditary molecule
