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.
While all bacterial cell walls (with a few exceptions e.g. extracellular parasites such as Mycoplasma) contain peptidoglycan, not all cell walls have the same overall structures. Since the cell wall is required for bacterial survival, but is absent in some eukaryotes, several antibiotics (notably the penicillins and cephalosporins) stop bacterial infections by interfering with cell wall synthesis, while having no effects on human cells which have no cell wall only a cell membrane. There are two main types of bacterial cell walls, those of gram-positive bacteria and those of gram-negative bacteria, which are differentiated by their Gram staining characteristics. For both these types of bacteria, particles of approximately 2 nm can pass through the peptidoglycan.
