WebSymbiogenesis (endosymbiotic theory, or serial endosymbiotic theory) is the leading evolutionary theory of the origin of eukaryotic cells from prokaryotic organisms. The theory holds that mitochondria, plastids such as chloroplasts, and possibly other organelles of eukaryotic cells are descended from formerly free-living prokaryotes (more closely … WebChloroplasts are the photosynthetic organelles of green algae and plants. Owing to their endosymbiotic origin, they contain their own genome with about 100 genes. Compared with their cyanobacterial ancestors, chloroplasts have lost most of their genes, due to either gene loss or transfer to the nucleus.
