Question

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

Explanation:

Endosymbiotic theory states that mitochondria and chloroplasts were once free - living prokaryotes. They were engulfed by a larger cell (through a process related to endosymbiosis). Symbiosis is a general term for close inter - organism relationships. Phagocytosis is a form of endocytosis for engulfing solid particles. Photosynthesis is a process that occurs in chloroplasts (but is not the process of their evolution). Endosymbiosis specifically refers to the symbiotic relationship where one organism lives inside another, which is the basis of the endosymbiotic theory for mitochondria and chloroplast evolution.

Answer:

C. endosymbiosis
