Another cell organelle that is believed to have originated through endosymbiosis is the chloroplast. Chloroplasts, found in plant cells and some protists, are responsible for photosynthesis and are thought to have evolved from free-living cyanobacteria that were engulfed by ancestral eukaryotic cells. This symbiotic relationship allowed the host cells to harness solar energy, leading to the development of complex plant life. The presence of their own DNA and double membranes in chloroplasts supports this endosymbiotic theory.
