Question

the endosymbiotic theory provides an explanation for the origin of chloroplasts. which trait of chloroplasts supports this explanation? chloroplasts do not reproduce. chloroplasts rely on proteins that are made by the cell. chloroplasts are larger than prokaryotic cells. chloroplasts have their own dna.

Explanation:

The endosymbiotic theory suggests chloroplasts originated as free - living prokaryotes that were engulfed by a host cell. Having their own DNA indicates they were once independent organisms, supporting the theory. Chloroplasts do reproduce, relying on cell - made proteins doesn't support the theory, and they are not larger than prokaryotic cells in a way that supports the origin theory.

Answer:

Chloroplasts have their own DNA.
