Illustrate the relationships among the membranes and compartments of a mitochondria and b chloroplasts by sketching simple concentric circles to represent the membranes. Plant cells contain two organelles originally derived from endosymbiotic bacteria. Differences Between Mitochondria And Chloroplast Mitochondria Vs Chloroplasts Their endosymbiotic origin explains why these organelles contain their own DNA nonetheless only a few dozens of genes are actually encoded by these genomes. . Sequences from red algae other than cyanidiales and from other algae that possess red-lineage chloroplasts as a result of secondary endosymbiosis should give body and substance to the. Thus two cell organelles involved in energy transformation reactions. Name two other organelles besides the mitochondria that contain DNA and have a double membrane. This captured energy into. Usually found in. The key difference between mitochondria and chloro...
