Here's a bit more detail:
* Chloroplasts are organelles (tiny organs) within plant cells.
* They are the sites of photosynthesis, the process by which plants convert sunlight, water, and carbon dioxide into energy (in the form of sugars) and oxygen.
* Chlorophyll, the green pigment that absorbs light energy, is located within the chloroplasts, specifically in the thylakoid membranes.
So, to answer your question directly, chloroplasts are the structures found in plant cells that contain chlorophyll.
