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 that chloroplasts originated from free - living prokaryotes that were engulfed by a host cell. Having their own DNA supports this as it implies they were once independent organisms. Chloroplasts do reproduce, relying on cell - made proteins doesn't strongly support the origin theory, and they are not larger than prokaryotic cells.

Answer:

Chloroplasts have their own DNA.
