Explanation:

The endosymbiotic theory posits that mitochondria and chloroplasts originated from free - living prokaryotes that were engulfed by larger cells through phagocytosis. Over time, a symbiotic relationship developed. Endosymbiosis is the long - term relationship that resulted from the initial phagocytic event. Photosynthesis is a process carried out by chloroplasts but not the cellular process involved in their origin.

Answer:

endosymbiosis
