Endosymbiotic Theory “Everything you need to know”

Endosymbiotic Theory Prokarytic cells developed into Eukaryotic Cells. They evolved by developing a symbiotic relationship with a primative aerobic bacteria and a cyanobacteria How? Endocytosis or engulfing Result? Evolution of eukaryotic cells

The Endosymbiotic Theory proposes that: Aerobic Bacteria became Mitochondria Cyanobacteria became Chloroplast

Endosymbiont Theory Support for this Theory: Same size and structure as bacteria Have their own DNA that is different from the DNA of the nucleus Divide similarly- binary fission

Endosymbiont Theory Chloroplasts and Mitochondria are descendants of once free-living prokaryotes that were engulfed by larger cells… establishing a symbiotic (mutually beneficial) relationship.
