Which cell type would you expect to find chloroplasts in?

• A. Animal cells
• B. Bacteria
• C. Plant cells
• D. Fungi

Answer: (C)

Chloroplasts are the sites where photosynthesis happens, using light energy to convert carbon dioxide and water into sugars that plants can use. Because this process is how plants make their own food, plant cells typically contain chloroplasts. Animal cells don’t carry out photosynthesis, so they lack chloroplasts. The same goes for fungi, which don’t perform photosynthesis and thus don’t have chloroplasts. Some bacteria do photosynthesize, but they don’t have chloroplasts either—their photosynthesis occurs in different membrane-bound systems. So, if you’re looking for chloroplasts, plant cells are the ones you’d expect to find them in.
