1. Endosymbiotic Theory “Everything you need to know”

2. 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

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

4. 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

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