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 proposes that mitochondria and chloroplasts evolved from prokaryotic organisms that were engulfed by a host cell. Phagocytosis is the process by which a cell engulfs large particles or other cells. In the context of endosymbiotic theory, the host cell would have used phagocytosis to engulf the prokaryotes that eventually became mitochondria and chloroplasts. Symbiosis is a general relationship, endosymbiosis is the result, and photosynthesis is a process in chloroplasts but not the process of their evolution. So phagocytosis is the cellular process involved in their evolution.

Answer:

B. phagocytosis
