Answer:

D. convert solar energy into chemical energy.

Explanation:

Chloroplasts are the organelles that carry out photosynthesis. They contain chlorophyll, which traps light energy from sunlight to power chemical reactions that produce glucose.

The solar energy is converted into chemical energy, which is used to synthesise glucose, along with carbon dioxide and water. The reactions produce glucose and release oxygen as a byproduct.
