WebChloroplasts are organelles found in plants and some algae that are responsible for photosynthesis, the process by which sunlight is converted into energy-rich molecules that the cell can use. Chloroplasts also have their own DNA, known as chloroplast DNA (cpDNA), which encodes for some of the proteins needed for photosynthesis. WebSince bacteria have their own genetic material, mitochondria and chloroplasts would be expected, as descendants of free-living bacteria, to have their own DNA and ribosomes. Thus, mitochondria and chloroplasts can carry out their own protein synthesis. Which of the following provides support for the endosymbiotic hypothesis?
