The theory of endosymbiosis claims that millions of years ago aerobic bacteria were taken inside of anaerobic cells through endophagocytosis The aerobic bacteria then fed on the half digested food molecules in the cell s cytoplasm and gained a great amount of energy which in turn benefited the host cell Since both organisms benefited they formed an endosymbiotic relationship the bacteria evolved into organelles such as mitochondria and chloroplasts and the aerobic cells evolved into eukaryotic cells Which of the following can be cited as evidence for the theory of endosymbiosis O A Mitochondria contain multiple linear chromosomes similar to those found in eukaryotic cells OB Mitochondria are typically above 50 microns in size whereas eukaryotic cells are typically smaller than 10 microns OC Eukaryotic cells appeared on Earth around 1 5 billion years ago whereas chloroplasts appeared on Earth only 2 5 million years ago The ribosomes of chloroplasts are more similar in structure to ribosomes found in prokaryotes than to ribosomes found in eukaryotes COD
