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 were once free - living prokaryotes that were engulfed by larger cells 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 use light energy to convert carbon dioxide and water into organic compounds and oxygen. Endosymbiosis is the specific process relevant to the evolution of mitochondria and chloroplasts according to the endosymbiotic theory.

Answer:

C. endosymbiosis
