Chloroplasts are organelles found in plant cells only, while vacuoles can also be found in animal cells. Animals cells may have small vacuoles (much smaller than plant cells), and often have more vacuoles than plant cells. Chloroplasts are the organelles responsible for plants' capability to carry out the process of photosynthesis. It is photosynthesis that generates food for other life forms and oxygen for all of us to breathe. Chloroplasts contain chlorophyll, a pigment, that captures the sun light and converts it into chemical energy. Vacuoles are large-sized fluid filled organelle in the cells. These can occupy as much as 90% of the internal cell volume, although under normal circumstances, they occupy about 30% of volume. Typically used for size and turgor pressure adjustment, these organelle can also serve as storehouses of nutrients and metabolites in a plant cell. 

Hope this helps.
