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 is a key trait as it is similar to prokaryotes, indicating they were once independent organisms. Chloroplasts reproduce, they do not rely solely on cell - made proteins, and they are not larger than prokaryotic cells.

Answer:

Chloroplasts have their own DNA.
