Sort of, all plant cells have plastids capable of differentiating into chloroplasts in the presence of light or amyloplasts, a kind of plastid that stores starch in tubers or the onion bulb. Plastids are not just assembled within a cell rather they all develop from a small, clear, stem plastid called a proplastid. They divide from their own fission as the cell divides so every plant cell carries these undifferentiated organelles. Proplastids become pigmented chromoplasts or leucoplasts. Leucoplastc further differentiate in to elaioplast, which store oil, or the starch storing amyloplast. Chromoplasts bear pigments, flower, fruit & root cells have them as well as leaves.

The onion is the root, it has green shoots where there are chloroplasts.
