Quizplus · Accepted Answer

Chloroplasts are organelles that contain chlorophyll and are responsible for photosynthesis. They are thought to have originated from cyanobacteria, which are photosynthetic prokaryotes that lived inside larger eukaryotic cells through a process of endosymbiosis. This idea is supported by evidence such as the fact that chloroplasts have their own DNA, similar to that of cyanobacteria, and that they divide by binary fission, just like bacteria.
