Endosümbioos

Kloroplasti sekundaarne endosümbioos

Endosümbioosi postulaadidThe 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.
