Explanation:
- The Endosymbiont Theory explains the evolution of membrane bound organelles such as mitochondria and chloroplasts.
- According to the theory, mitochondria evolved when an ameoba like organism engulfed bacteria capable of cellular respiration.
- Similarly, chloroplasts were developed when the ameoba like organism engulfed cyanobacteria or blue-green algae capable of photosynthesis.
- These organisms survived inside the ameoba over millions of years to develop into mitochondria and chloroplasts.
- The fact that mitochondria and chloroplasts have their own circular DNA and ribosomes is evidence of the endosymbiont theory.
