the fact that mitochondria and chloroplasts contain their own DNA that is genetically similar to prokaryotic DNA is supporting evidence for the ______theory.

A. Extrusive

B. Exosymbiotic

C. Evolution

D. Exogenous

E. endosymbiotic

Expert Solution

Ans : E. Endosymbiotic

Explanation : Endosymbiotic theory states that eukaryotes evolved from prokaryotic organisms due to similarities in the genetic material of eukaryotic mitochondria and chloroplast to prokaryotic organisms like cyanobacteria. Endosymbiosis is the existence of an organism within another organism in a mutualistic way. Therefore, prokaryotic organisms like bacteria and archaebacteria that were internalized by eukaryotic cells were believed to have evolved into cellular organelles like mitochondria and cloroplasts.

Explanation for other options :

A. Extrusive : rocks that have been extruded to the surface of earth in the form of lava from a volcanic erruption.

B. Exosymbiotic : The symbiosis in which an organism lives on the external surface of another organism in a mutually beneficial way.

C. Evolution : The change in the characteristics of a species over a period of time due to variation and natural selection.

D. Exogenous : anything that originates from the exterior of a body

The first theories to explain the similarities between bacteria and mitochondria or chloroplasts suggested that an early eukaryotic cell actually engulfed but failed to fully digest a free-living prokaryotic cell. Why is such an event unlikely to account for the origin of mitochondria or chloroplasts?
