Question

select the correct location on the image. keiko’s teacher was discussing the theory of endosymbiosis. she asked keiko to mark the organelles in the diagram that most closely resembled prokaryotes. which organelles should keiko mark?

Explanation:

The theory of endosymbiosis suggests that mitochondria and chloroplasts were once prokaryotic organisms that were engulfed by a larger cell. Mitochondria (and chloroplasts) have their own DNA, ribosomes, and a double - membrane structure, which are characteristics of prokaryotes. Among the organelles labeled in the diagram, mitochondria and chloroplasts are the ones related to endosymbiosis. If we look at the diagram, the mitochondria are labeled, and they are the organelles that most closely resemble prokaryotes according to the endosymbiotic theory.

Answer:

mitochondria (or chloroplast, but mitochondria is a very common and clear example here. If we have to choose from the labeled ones, mitochondria is a key organelle for endosymbiosis. So the answer is the mitochondria - labeled part in the diagram)
