The chloroplast is the place in a plant cell where photosynthesis happens. Your rose bushes have chloroplasts, but you don’t.
Chloroplast is the combination of two biological terms, plastid (an organelle in a plant cell), and chloros, which means green. If you’re reading about plant biology, you’ll probably recognize chloros in chlorophyll, which is one of the pigments important to photosynthesis, which takes place in chloroplasts.
