SILVA: why is chloroplast defined as bacteria?

Does that mean 16S sequences from one plant cell can map to both eukaryota and bacteria simultaneously?

Correct. Mitochondria will also map to bacteria:

Mitochondrion

@SteveMcL

Phylogenetically, is a plant a eukaryota, a prokaryote or both ? That might be more of a philosophical question.

Philosophical indeed. Phylogenetically it would be considered a plant. But philosophically I suppose we might say both.
