Answer:
1. Mitochondria
2. Chloroplast
3. the formation of eukaryotic cells
4. DNA
Explanation:
The theory of endosymbiosis was proposed by the Lynn Margulis in 1967 which suggested that the eukaryotic organelles like the mitochondria and chloroplast evolved when another prokaryotic cell engulfed the prokaryotic bacteria.
The mitochondria were formed when the chemosynthetic bacteria were engulfed by the bacteria and the engulfed bacteria formed a symbiotic relationship. Similarly, the chloroplast was originated in the same way when the photosynthetic bacteria were engulfed by another prokaryote.
The evidence which supports their ar:
1. The same size of the organelles to the bacteria
2. The presence of the circular DNA of the organelles like bacteria
3. The similarity in the 30s and 70s ribosomal subunits.
