Question

according to the endosymbiotic theory, which cellular process was involved in the evolution of mitochondria and chloroplasts?
symbiosis
phagocytosis
endosymbiosis
photosynthesis

Explanation:

The endosymbiotic theory posits that mitochondria and chloroplasts originated from free - living prokaryotes that were engulfed by a host cell through endosymbiosis. Symbiosis is a general term for a close and long - term biological interaction. Phagocytosis is the process of a cell engulfing solid particles. Photosynthesis is the process by which plants and some other organisms use sunlight to synthesize foods with the help of chloroplasts. Endosymbiosis is the specific process relevant to the origin of mitochondria and chloroplasts according to the theory.

Answer:

C. endosymbiosis
