is the mitochondria a bacteria
Mitochondria and chloroplasts are thought to have arisen from bacteria, engulfed by primitive cells in a process called endosymbiosis. Mitochondria probably evolved when cells took up aerobic bacteria, while chloroplasts were derived from photosynthetic bacteria, such as cyanobacteria.his process of replication is called binary fission and also occurs in bacteria. Replication by mitochondria and chloroplasts is independent of the host cell's replication cycle. Plant and animal cells replicate by a complex process called mitosis or meiosis.
