Question

which organelle is believed to have evolved through an endosymbiotic relationship with bacteria? ribosome mitochondria viruses

Explanation:

The endosymbiotic theory suggests that mitochondria (and chloroplasts) originated from free - living prokaryotes (bacteria). These prokaryotes were engulfed by a larger cell and over time, a symbiotic relationship developed. Mitochondria have their own DNA, similar to bacterial DNA, and their own ribosomes, which supports this theory. Ribosomes are not the result of an endosymbiotic relationship with bacteria. Viruses are not organelles.

Answer:

Mitochondria
