Researchers have proposed a model of chloroplast evolution. According to the model, chloroplasts evolved from a small prokaryotic organism that was engulfed by an ancestral eukaryote. The engulfed prokaryote then formed an endosymbiotic relationship with the eukaryotic host.

Which of the following observations best supports the model?

• Chloroplasts are separated from other subcellular compartments by semipermeable membranes.

• Prokaryotic and eukaryotic organisms both acquire nutrients from the surrounding environment.

• Eukaryotes evolved after prokaryotes and have more complex structures.

• Chloroplasts and some prokaryotes share similar photosynthetic reactions.
