Transcript Evolution Review

Eukaryotic cells may have evolved
through endosymbiosis.
• Endosymbiosis is a relationship in which one
organism lives within the body of another.
• Mitochondria and chloroplasts may have
developed through endosymbiosis.
Endosymbiosis
• Animation of Endosymbiosis
• Mitochondria and chloroplasts have
their own DNA
• Mitochondria and chloroplasts can
copy (replicate) themselves
• Mitochondria and chloroplasts are
about the same size as prokaryotes
• Mitochondria and chloroplasts have
circular DNA
