A symbiotic relationship forms because this prokaryote was able to supply useful materials to the host cell. Photosynthetic bacteria supplied sugars, while others performed aerobic respiration, supplying ATP to the host. Over time these organisms co-evolved with this relationship and lost the ability to survive independently. Evidence: Double membranes DNA & ribosomes Same size Divide on their own
