What is the function of chloroplasts in plants?

Explanation:
Chloroplasts are the sites of photosynthesis, where light energy is converted into chemical energy stored in sugars. They use chlorophyll to capture light, and the light-dependent reactions generate ATP and NADPH. Those energy carriers drive the Calvin cycle in the stroma, which fixes CO2 into sugars that can be used by the plant for growth and metabolism. This is the primary function of chloroplasts: turning light into stored chemical energy in carbohydrates. While chloroplasts do contain pigments like chlorophyll, their main role isn’t pigment storage, and they aren’t responsible for breaking down waste products—that task belongs to other organelles. They also aren’t the organelle that generates ATP through cellular respiration (that’s the mitochondrion).
