Which statement about chloroplasts is true?

Explanation:
Chloroplasts are the site of photosynthesis and contain chlorophyll, the pigment that captures light energy. In the chloroplast, light-dependent reactions take place in the thylakoid membranes to produce ATP and NADPH, which then power the Calvin cycle in the stroma to convert carbon dioxide into sugars. Oxygen is released as a byproduct of this process. While chloroplasts do contain some genetic material, the cell’s main store of genetic information is in the nucleus, not chloroplasts. The mitochondria are the primary site of cellular respiration, and chloroplasts do not regulate cell division. So the statement that chloroplasts contain chlorophyll and are the site of photosynthesis is the correct description of their main role.
