The organelles that use light energy to make carbohydrates from carbon dioxide and water are chloroplasts.

Here's a breakdown:

* Chloroplasts are found in plant cells and some algae. They contain the green pigment chlorophyll, which absorbs light energy.

* Photosynthesis is the process by which chloroplasts use this light energy to convert carbon dioxide and water into glucose (a type of carbohydrate) and oxygen.

* The equation for photosynthesis is:

* 6CO₂ + 6H₂O + light energy → C₆H₁₂O₆ + 6O₂
