Explain the evidence that supports the endsymbiotic theory of chloroplasts and mitochondria

Mitochondria and chloroplasts cannot grow outside the host cell. The evidence is based on the fact that chloroplasts are the same size as prokaryotic cells, It splits by binary fission and, like bacteria, has Fts proteins on the cleavage plane.

this protocol provides a detailed procedure for co-immunoprecipitation (co-ip) to identify protein–protein interactions.
