Does photosynthetic bacteria have chloroplasts?

No. Bacteria are prokaryotes, meaning they have no specialized organelles enclosed by membranes. The ones that are photosynthetic simply have pigments that work similarly to chlorophyll.

Cyanobacteria (blue-green algae) do not have choroplasts but they certainly do have chlorophyll. It is found in the cytoplasm, not in a membrane-bound organelle. There exists two forms of chlorophyll (a and b) which absorb different wavelengths. These bacteria only have the a-type.
