A plant cell is exposed to sunlight. Which two organelles are involved in using sunlight to produce and release energy, and how do they work together?

• Chloroplasts capture sunlight to make food, and mitochondria release energy from that food.

• Nucleus and ribosomes work together to produce and release energy.

• Vacuole and cell wall are responsible for energy production and release.

• Golgi apparatus and lysosomes use sunlight to produce and release energy.
