Protistid - vetikad, algloomad, munasseened II Ene-Külli Tamm 2007 Protistide sugupuu Volvox Caulerpa – rakutuumi palju, rakuvaheseinad puuduvad Endosümbioos Kloroplasti sekundaarne endosümbioos Endosümbioosi postulaadid The endosymbiosis theory postulates that The mitochondria of eukaryotes evolved from aerobic bacteria (probably related to the rickettsias) living within their host cell. The chloroplasts of eukaryotes evolved from endosymbiotic cyanobacteria. Eukaryotic cilia and flagella may have arisen from endosymbiotic spirochetes. The basal bodies from which eukaryotic cilia and flagella develop would have been able to create the mitotic spindle and thus made mitosis possible.
