Question

Quizplus · Accepted Answer

Mitochondria and chloroplasts are believed to have originated from a process called endosymbiosis, whereby a bacterial cell was engulfed by a eukaryotic cell and developed a symbiotic relationship. The bacteria that gave rise to mitochondria were likely related to present-day species of Rickettsia and the bacteria that gave rise to chloroplasts were likely related to present-day cyanobacteria. Therefore, the origin of mitochondria and chloroplasts is bacterial.
