The Endosymbiotic theory talks about:
A prokaryote engulfing another eukaryote and functioning properly
A mitochondria-like prokaryote engulfing a chloroplast-like prokaryote and functioning together
A prokaryote digesting another prokaryote and using its DNA
A prokaryote engulfing another prokaryote and functioning properly
Evidence for the Endosymbiotic Theory is that chloroplasts mitochondria have the same size and structure as bacteria.
